Airline reveals its concerns about new Airbus lavatory/galley option


As airlines work to increase passenger density on existing airframes the push to reduce everything else on board is very real. For the Airbus A320 family of planes the Space-Flex v2 lavatory/galley option being developed in partnership with Zodiac is one solution to this challenge and multiple airlines are understood to be considering it. Space-Flex v2 has certain benefits, namely it adds extra space for seats, but there are also very real challenges associated with the design, especially for full-service airlines. One potential customer has been reviewing the offering, but tells RGN, “No group other than finance was enthusiastic about it.” From a passenger comfort and employee ergonomics perspective this airline saw it as a poor fit, and also expressed safety concerns.

For passengers the main issue could prove to be lavatory size. Space-Flex v2 does offer a single American with Disabilities Act (ADA)-compliant lavatory, which is a positive feature for a narrowbody aircraft. But unlike Space-Flex v1 – which features a swinging partition between two lavatories to accommodate passengers with reduced mobility – Space-Flex v2’s lavatories have a fixed partition, and a wheelchair-bound passenger must transfer to a tip-up seat and then, unassisted, to the toilet seat. The lav is a tighter fit for passengers. And the layout creates access challenges as passengers negotiate between the jumpseat to enter/leave the lav, suggests the airline that spoke to RGN on condition of anonymity. This also creates a greater risk for employees or other passengers being struck by a door as they open/close in such tight quarters. And if the flight attendants have carts out before or after a meal/drink service access to the lavatories may be blocked because of the limited floor space available.

For the airlines, despite gaining the extra seating space, there may be other drawbacks as well. Some of the cited challenges, such as only one coffee pot in the rear galley, seem a bit trivial. Other challenges press against FAA regulations, presenting scenarios which flight attendants may struggle with or reject. The carrier that spoke to RGN suggests that rubbish collection, for example, becomes significantly more difficult with the limited space. The reduced number of cart positions means no dedicated trash carts in the Space-Flex v2 layout; all collection would happen in bags.

That alone is not a deal breaker, but there is minimal space to store the bags once the trash is collected; most likely flight attendants would need to transfer the contents from bags to a trash bin or compactor. The limited space would also preclude separation of recyclable materials and could potentially cause overflow of the space, requiring full rubbish bags to be stored in overhead bins (yuck!) or in the lavatories (FAA violation), suggests the airline. The FAA tells RGN, “Airbus has not applied to the FAA for the Space-Flex interior, so we do not have any information on this interior layout and cannot comment at this time.” EASA did not respond to a request for comment.

Airbus head of aircraft interiors marketing Zuzana Hrnkova addressed the garbage challenges when she told RGN that the design was finalized with “validation from airline representatives” so that there has been some buy-in from the stakeholders. Moreover, she noted that most of the customers so far “don’t really [offer] a full service….so there is not a lot of waste generated”. That may work for some LCCs but for the full-service carriers other options such as an integrated trash compactor (still in development) would be used to help offset the loss of space. If still more space is needed, additional galley monuments can be installed, though that reduces the number of additional seats the airline will be able to fit in the plane.

Other safety concerns raised by the airline include the double-deep ovens and increased burn risk when accessing the rear rack and a more constrained workspace, increasing risk of strains and sprains. Similarly, some of the cart positions become three-deep rather than the current two-deep maximum. The logistics of moving the carts around in the galley space – and, particularly, storing the full cart behind the half cart during turbulence – presents a challenge which could further expose flight attendants to greater risks. With such injuries costing the airline $25,000+ per incident on average these risks cannot be overlooked, says the airline.

Specifically addressing the service preparation and galley cart issue, Airbus’ Hrnkova suggested that minor adjustments to airline operational procedures could solve many of the issues. “After the take-off cabin crew can start preparing the service [while the seat belt sign is illuminated]. Cabin crew can start their service before the passengers are allowed to move in the cabin,” she said.

When talking about the potential for spatial issues related to lavatory access and jumpseats, Hrnkova noted,

“The seat is used for takeoff and landing. It is not used during the flight phase. On the type of sectors which the A320 operates the cabin crew are busy with the service, with onboard sales and afterwards preparing the aircraft for landing. So the seat is not used during the flight phase.”

This is true for shorter flights, however a number of airlines use A319s and A320s on longer stage lengths. The North America market, in particular, sees Air Canada, American, United, JetBlue and Virgin America all operating A320s with an average block time of greater than 140 minutes, according to flight data based on OAG schedules for 3 August 2015.

Longer stage lengths also generally mean more “stuff” in the galley, whether snacks, drinks or garbage collection. Airbus’ Hrnkova spoke to this topic, noting that there is an add-on option for the Space-Flex v2 layout which can meet those airlines’ needs. “What we believe is going to happen is that version 2, with increased half-size trolley capacity, will mainly be selected by low-cost operators. However, for full-service carriers, if they have more catering requirements, there is still possibility to integrate on the right hand side the three-trolley galley and compensate the galley capacity. In any case there is a gain of three seats which is very good and the capability to offer full service to passengers.”

The loss of roughly a third of the storage space on the A320 already means cuts must happen somewhere. Compounding those cuts with design options which could increase risks to the crew presents a conflict. Thus far the Space-Flex product is seeing adoption in the LCC markets. Vueling has deployed v1 of the offering (the Airbus-own option) and JetBlue is expected to use the newer v2 (Airbus/Zodiac option) as part of the company’s retrofit of its A320 fleet, adding 15 seats.

Can the Space-Flex v2 design work on board, even for a full-service carrier? Absolutely. But compromises must be made to get to a workable solution. And, based on the design validation and planning from Airbus it seems clear that there are very different use cases, some of which will be more successful than others.

Airbus explains Space-Flex v1 in the video below; as mentioned, there are material differences between v1 and v2.


  1. Nice article, it is correct that the seats are typically only used during TTL, or taxi take off and landing for short haul flights. Unless its a long haul flight, then there will be opportunities for discomfort while the seats are being used. But the airlines stands to gain a lot with 6 more seats, while trying their best to accommodate everyone. Its a huge engineering task to design manufacture and certify these monuments per FAA regulations, I talk more about it at http://www.stressebook,com.

    They don’t look that big to me but I guess I would have to see it for myself. The airlines like Qantas don’t really care about disabled passengers as I said on facebook page they have made the Lavs so very small there almost painful to use

  3. KTM

    As a Professional Flight Attendant, for a U.S. Major – I fly the A320/A319 cross-country, daily; IAD-SFO, EWR-SFO, PHL-SFO, etc. Onboard our A320/319’s we have two LAV’s at Door 2L. One just forward of 2L and one, aft of 2L. The FA’s jumpseat is located on the forward ‘bulkhead’, at Door 2L. When the FA’s are setting up the Carts for the Service, many times, we park a Cart in front of the Aft LAV (due to limited space) to set-up the Meal (Buy Onboard) Cart, just prior to taking both Carts out into the aisle. If the seatbelt sign is turned off – Passengers head for the LAV’s, thereby causing a log jam in the Galley/LAV area at Door 2L/2R. The FA’s then have to adjust the Carts, which at times is impossible, due to the “Number of Passengers” waiting to use the LAV. (They, the Passengers, simply look at you when you ask them to move out of the way, so you can adjust the Carts….frustrating.) After the Service is completed, we the FA’s then sit, yes sit on our Jumpseat at door 2L – this causes the Passengers who need to use the LAV, aft of 2L to have to open the LAV door and squeeze past the Jumpseat. Often times, the Passenger(s) just bang into the FA’s, with no apologies, no excuse me… as if the FA can go somewhere to get out of their way? Most times, it the FA’s sit on the Jumpseat to ‘Take a break’ and get off our feet for a few minutes, the Aft LAV door is Locked-Off, forcing all Passengers to use the forward LAV at 2L. This New ‘Space Saving’ design will cause much chaos, in a space that is already tight to begin with. Boeing has already designed their new ‘Slimline LAV’s’ for the B737 and it is horrid. Passengers complain on every flight, how tight and small the LAV’s are. However, the Airline was able to get an additional 6 Slimline seats into Economy. Comfort be damned.

    ADA doesn’t apply to airlines. You care thinking of ACAA

    The E90 already has this potencial hygiene issue in production

  5. Todd

    I fly 125,000+ miles a year; I agree with KTM in all respects (although I actually speak to the FA if they’re in a lav-proximity jumpseat, rather than just blindly attacking them with a door 🙂 )

    I would also have concerns about the idea of starting cabin service ‘before the seatbelt sign is turned off.’ In most cases, once the seatbelt sign is off, many passengers need to use the lavs, especially if there’s been a long taxi (such as at congested airports like JFK). So that would create an aisle logjam as well as a lav logjam.
    Not ideal.

    Fore and aft lavs available to economy passengers, as on most 757s, work much better to avoid these jams, but I guess that doesn’t work for the cattle-car concept.

    Delta is going with the Spaceflex v1 on their A320/A319 refits. On a common stage length such as MSP-DEN, that should be OK. But with 144 coach pax, two tiny lavs adjacent to the galley, and conflicting jump seats, I can see long lines in the newly narrower aisle, and frustrated pax and FAs on some typical 3.5 to 4 hour A320 sectors for DL.
    21st century pro tip: Don’t drink much before or during flight.

  7. Jean Livingston

    I see the new design as an accident waiting to happen. Why not instead use the space that is suppose to house six additional seats for 2 jump seats and room for carts to move out of the passenger lavatory line. I can just picture a wheel-chair bound person in the line that usually forms after the seat belt sign goes off, waiting for the two lavs to become one and then the remaining passengers “patiently” waiting for the facilities to again become two again. This newly designed layout may look good on paper but not in action.

  8. Jon Allen

    “Space-Flex is a key enabler to achieve up to +6 seats”

    From what demented marketing committee did that line emanate?

  9. julius grafton

    If the airlines MUST squeeze in extra seats, why not leave 1 x lav and install 1 ‘space flex’ style lav in the galley, so there is still a little more cart room and a little less Jump Seat argy-bargy? Oh wait, that would be a compromise, wouldn’t it?

  10. Anonymous crew member

    Having used this layout for the past year I can give a flight attendants opinion from experience. My first issue is the quality of the materials used. The lower two sets of canisters are three deep. This causes many problems. Constantly removing canisters to get at what you need uses up space. If you need to get to the last canister you must remove the two in front (where to put them?). It is not possible to reach the third canister without using the pulley system that slides it forward. This breaks very often. My airline has many planes with this set up and almost all of them have at least one broken pulley and these are not being replaced. This means you then CANNOT access the last canister to even search it when carrying out preflight checks (safety). I have seen people stand on canisters and lean all the way into the space but one slip and you’d break your neck.
    Space for trash was mentioned in the article. My airline uses bags but does not have any means to compact and recycling is just putting those materials in a different bag. With more than one bag in the back galley it becomes difficult to open the toilet door on the right so we walk the trash back through the aisle to put it in the front galley.
    Space to turn double sized trolleys is very limited and there can be no other crew or passengers in the galley when doing this. Crew were obviously not a consideration in this layout as again two of the trolley stashes are three deep or one double and one single so you use limiting what little space you have when trying to get at something in the rear trolley.
    The seat on the door has caused numerous problems. Mainly that the seat is so heavy that it affects the doors closing and locking ability resulting in the toilet being closed and often sealed for weeks at a time. Stringers materials have been used in the newer ones with very limited success. Also passengers do not even realise that there is a toilet there because having the seat on the door just looks so strange and un-doorlike. Without crew pointing it out most people just wait for the other one. When they do use the toilet with the seat on it they often have problems closing the door as it is just so heavy and often requires assistance to push is closed from the outside.
    The toilets themselves are ridiculously small. The article mentions the disabled access is by sliding onto a flip down seat and then onto the toilet unassisted. If the person is any bigger than a child then this feat is impossible. I’m sure they did lots of testing but anyone of average size would slip off the small slide seat as it is only about 5 or 6 inches at its widest point.
    The whole layout inside the toilet is just strange. Too many little cubby holes means more searching for crew but also the trash flap is not obvious when looking to throw the papers towels and so many people just leave them in the sink or throw them on the floor or use the sickbag dispenser. The hand towel dispensers can only manage a small handful of hand towel and so need constant replenishing. Above the smallest sink you have even seen is a panel which has a callbell and a socket for a shaver. The panel warps because if gets wet constantly and the socket is a serious hazard as it so close to the tap. Getting to the hot water switch under the sink is a challenge and the catch often breaks meaning there is yet another place that cannot be adequately searched.
    Finally, the ice box. Small than a box for baby shoes. We often use this config for longer flights but the ice runs out half way through the first service and from then on, tough luck. Next to the ice box is a small shelf with a small sink to pour waste water. To do this though the small shelf cannot have anything on it at all. There is a small fold down grill which must be folded up as trying to pour through the grill makes a big mess. You cannot open any of the small cupboards or the ice box either if there is anything on the shelf.
    All in all this is a terrible design that gets nothing but complaints from crew. Cheap materials used, bad layout and no thought for crew at all.

    All in all, there is far less space for crew, smaller crew seat, stupid crew seat, stupid toilets, stupid crew seat on door, no room to do anything without bashing into everything.

  11. Rebel !

    We are using it on our A 320’S retrofit aircraft (186PAX)
    The width of the toilet is the width of the crew seat. If you’re large, it’s challenging to go in this tiny toilet.
    The PAX touch your seat to go in and go out from the toilets, and everybody knows how clean are our passengers.
    In case of severe unexpected turbulence,,if you’re three cabin crew at the back, you need to let the pax in the toilet !
    The think in the toilet is so small, that you can’t wash your hands without dropping water everywhere….
    It’s almost impossible to remove the double cart close to the door during climbing as their is no space to turn it.
    The pulleys to remove the third canister are already broken after 6 months of use !
    When you need something in the third canister, you need first to remove 2 canisters and they’re no space to store them….
    The single trolley should be stored at the front of the double cart for take off and landing. And we’re are using the double cart for the service….
    The paint of this galley is already damaged after 6 months of use.
    Thank you zodiac to turn my job in a nightmare !

  12. Anaconda

    It is up to each airline to decide what products they want to install. Certainly not the fault of Airbus or Zodiac for that matter.

    It’s like faulting Smartcar for selling such a tiny car.

    If you have never operated on this configuration try and avoid it, from a fight attendants perspective it is Danerous! What this article doesn’t cover on Space Flex 2 is that the rear galley is harder to navigate having more canisters and trolleys in storages and no space to move them in the galley. When your in flight and need to access stock it’s a matter of didn’t space to put things whilst you find things whilst allowing and not blocking passenger access to the toilets. The rear galley has what I consider to be the biggest and most dangerous thing to but put on an aircraft; the extended galley surface. Due to the extra storages and the 3 deep canisters and trolleys the surface has been extended into the galley causing an overhang of sorts to be needed in the rear galley to accommodate it. It is hard for me to fit through this gap in a hurry like landing or turbulence I’m of average size and I would doubt any passenger including a pregnant passenger would be able to safely navigate this space unscathed, not even thinking of an emergency situation I think we would struggle to evacuate at a safe pace to ensure the safety of all passengers onboard. The space flex 2 as a cabin crew / flight attendant scares me and it should scare passengers too! As for the PRM lav at the rear and it’s layout with Lav F & G they are Tiny, and I do mean Tiny. Most passengers struggle in this space and mothers with infants struggle also as there is no storage space as such to place things. Most times I’ve been on these aircraft Lav G is inop due to technical reasons so much so it is typically powered off. For the sake of an extra 6 seats it’s a terrible trade off even for a capitalist like myself. Somehow it must comply with EASA but I don’t know how, it’s just a cheap option for airlines who want more sears and not the cost of buying bigger planes.

  14. Anon

    Sorry I forgot to mention the other hidden dangers as crew in this galley config.
    Preflight safety and security checks! So much harder and physically draining having to move more canisters and trolleys to complete your checks in the galley. But the toilets pose the biggest safety issue. The bin flap pushes open and the more it does the more things that get piled behind it they don’t fall to side and fill the bin space they just linger behind the flap which then causes it problems closing so your in and out during the flight pushing it into the bin so to contain a fire in case it happened. Doing preflight checks is so difficult, you have this tiny space where to us struggle to fit 2 children in and you have to check al large compartments and storages you can barely move inside them and sometimes I feel after I’ve done a check I’m felt feeling did I check that small space behind the sink or in the cupboard or under the bin. There’s so many small spaces. How a disabled passenger manages to move inside this I don’t know. My airline has issues where the Lav keep forgetting if F or G is out of use due to the seat being broken or the locking pin to the floor to secure to door to use the seat is broken your sharing a crew seat at the back in an already smaller galley. This thing is a crew members nightmare! Airlines don’t give a crap about us and seamingly just as little about safety of their customers over adding a few extra seats for profit. Worst thing about this whole Space Flex V2 was that V1 was framed a failure by any airline who took it as doors kept breaking pulleys kept snapping under the extra weight and the PRM access at the rear with the swing door became so troublesome they simply removed it from the references I’ve read it was causing airlines more downtime fixing these problems than it was to keep serviceable. As far as I’m concerned airlines have gave up on Safety, by remember Crew Have Not!

  15. another worried runway girl

    My employer is one of the new airlines configuring the aft galley into Space-Flex V2. Our procedures demand that crew is always seated when the seatbelt signs are on. Also during the flight, in case of turbulent weather we immediately return to galleys, secure it and take our seats. The problem is that the CCM seat in the aft galley is located opposite to the toilets and if someone is in the toilet, you cannot take your seat before the toilet is empty (I guess it’s the same when the seat is in front of the toilet door). Our average flight time from home base is more than two hours up to four hours and even more. Quite often our longest flights are during the night time. The use of toilets is dense during the inflight service, we cannot prepare the service when the seatbelt sign is on and we don’t even want that, because it is for our safety. The extra table is unpractical during these crowded moments and the trolley being prepared has to be placed in front of the toilets. A319/A320 are especially turbulent sensitive in the aft galley compared to forward part. The service preparations are very difficult as we sell a lot on these fairly long short haul flights. The new trolley for two is shaky and fell already on my fellow workers leg as she saved a passenger from under it. For the night flights there are no place for the cabin crew to even sit, it is unpleasant to eat in the aft galley as everyone are pulling the curtain on their way to the loo. How can there be a waste bin now a days that cannot be opened during the flight? Isn’t that a safety hazard what comes to bomb search procedures during the flight? Pulling out the third canister/trolley is an occupational safety hazard. The mechanism does not work as the trolley tires get jammed. It seems that that quite often these third units are left unused if not coming out. We are not crawling in to get them out. Problem is especially when stowing the units for landing and during turbulence. On one flight there was already ASR filed as the units could not be stowed for landing. How could you design something like this without considering the employees who work on these aircrafts. How did this pass all the safety tests? The unions must respond to this neglecting of cabin crew working conditions!

  16. David Hoffman

    When some airliner designers got wise some time back and put all the lavatories in front of the aft galley area that created a full width area for gally work with almost no passengers crossing or entering galley space to use lavatories. Great improvement, but the aisle blocking issues were still there. A really radical plan would be to rotate the lav entrances 90 degrees to the front and take out three rows of seats. That would reduce the aisle blocking by creating spaces to the port and starboard of the aisle for passengers to wait for a lavatory vacancy and allow for full unobstructed lavatory door opening. Yes, I just advocated removing 18 seats from existing normally configured single aisle aircraft. Passenger comfort and better service becomes a selling point, not just low fares. Another radical idea is that the agencies that supposedly exist to create and enforce real safety standards mandate some version of this idea for future airliner purchases.

  17. Kat

    This design is the absolute worst!
    I wish these ‘designers’ had to actually work/fly on these spaceflex planes. We have now invited the entire plane to congregate in our tiny galley. We have the never ending line for the lav (which starts well before the seatbelt sign goes off) the large number of passengers who are ‘just stretching my legs’, the hardcore exercises who think the galley is a yoga class, and several parents with infants, who feel the only way to keep them from screaming is to stand in our galley. It is an unbearable, unsafe situation!
    Passenger are now in the galley nonstop. Touching our service items with their unwashed hands, coughing, sneezing, and trying to sit in our jumpseats. Then are indignant when we have to ask them to not touch anything.

    Flight attendants do sit in their jumpseats during flight, but now it is impossible. Because we are in the way.

    Other FA’s have made excellent points on the safety issues, with this design, so I will not cover the same ground, but will add one other safety concern. We had a passenger accidentally lock a FA in the lav, that has the jumpseat on the door. As that door has a special lock, which can not be unlocked from the inside. FA can no longer use that Lav, inflight.
