I’m on the road 11 out of 12 weeks and during that time I’m flying American, Delta, United, Alaska, Southwest, Qantas, British Airways and Volotea.
I don’t fly United a ton. Their route network and frequencies don’t help me a whole lot out of Austin, where they’re the fourth largest airline. I long avoided them because they had the worst wifi in the industry and I try to be productive inflight. Their inflight internet has gotten better, even before bringing on StarLink which is the best wifi in the skies (I’ve used it on JSX and on Hawaiian).
I hadn’t experienced this on my most recent United flights, but this past week flight attendants locked the lavatories for descent. That’s not something I’ve ever seen on another U.S. airline. It’s something that United does increasingly often, it seems – especially when there’s turbulence expected.
- Every transport‑category lav has an external latch hidden behind the “LAVATORY” or “NO SMOKING” placard. Sliding it lets crew lock or unlock the door from the outside. This is standard across Boeing and Airbus aircraft.
- When they lock it this way, the door won’t open from the outside. Passengers can’t enter (anyone already inside can still get out).
For the past year and a half, United has required cabin crew to be seated and buckled no later than the “double chime” (~10 000 feet) to mitigate flight attendant injuries. During this time, they generally don’t make lavatories available to customers.
- It’s common on most airlines to tell passengers to be seated, seat belts fastened, tray tables up and seats in their upright position – and carry-on items stowed.
- During this time, if you get up to use the lav, a flight attendant nearby will likely tell you “the seat belt sign is on” which many passengers incorrectly interpret to mean they aren’t allowed to use the restroom (they’ll get in some sort of trouble for disobeying crewmember instructions).
- In fact, the crewmember is usually doing all they need to – if you get hurt it’s not their fault!
- But on United, they actually prevent you from doing it.
If a lavatory door were left unlocked, a passenger could enter after crew are seated. They might stand up (violating the fall 2023 policy).
Approaches into Denver in particular are often bumpy. That’s where I heard the announcement about locked lavs. This prevents passengers from using the facilities during the choppiest air. The airline guides cabin crew, “if the belt sign is on, do not make lavatories available.”
Note that locking the lavatories is not an FAA rule. 14 CFR 121.317(f) requires passengers to remain belted when the sign is lit. Keeping the doors locked reinforces this.
You’re going to see this most:
- in significant turbulence
- on Denver approaches
- on United’s Airbus A321neo aircraft where jump seats block the path to the lavatories
If you’re flying United, you need to treat the end of flight announcements as your last chance to use the bathroom.
But what do you do if you really have to go? You need to make a quick calculation.
- Trying to force the door or argue can get you in some trouble for disobeying crew instructions. At least in theory.
- A couple of United flight attendants I spoke to both told me that they’d never give a passenger a hard time for unlocking the lavatory themselves if they had a bathroom emergency. They made the announcement. They locked the door. They fulfilled their job obligations. As long as you’re polite, not a jerk, they aren’t going to pursue it.
- But one flight attendant’s perception of jerk is different from another’s! And every situation is different. Plus, someone could be having a bad day.
Weigh the risk of getting written up, or even speaking to authorities after the flight, against the likelihood you can make it onto the ground, and taxi to the gate, before reaching a bathroom (either the airplane’s lavatory prior to deplaning – though you’ll have to fight through a sea of people in the aisle most likely, or the time it takes into the terminal).
happened on a Spirit flight – I thought you covered it – and someone (a woman) just pulled down her pants in the galley and let it rip
@Tim Dunn — while I don’t remember that specific incident, I do seem to recall a post regarding a woman on a Southwest flight stripping naked and pooping in the seat.
Late lavatory visits also reminds me of a post where Gary highlighted people hiding in the first class lavatories to try and deplane first.
Deferring to call back expert, @1990!
@Tim Dunn — I would say, ‘dinner and a show,’ but Spirit doesn’t serve meals…
@L737 — Ah, yes, not too long ago, April 26, 2025, Gary posted: “‘Grounded For Deep Cleaning’: Chicago Cops Board Southwest Plane After Naked Woman Poops On Seat.” Classic!
I have seen this on AA and BA flights. While not common it does happen
Alaska Airlines has been locking the lavatories for as long as I can remember – many years. They even announce it: “The lavatories are now locked for the remainder of the flight”.
(For those ‘in the know,’ if it’s a true ‘emergency,’ and, like, no ones in there, but they locked ‘em, just flip open the latch to open manually… I mean, you’re gonna get ‘banned’ by the airline anyway, so, might as well ‘take care of business’ in the toilet than on the floor.)
I understand the safety argument, but locking people out of toilets seems extreme…especially if the duration is long. We can’t be trusted to decide when to get up during turbulence but we can be trusted to decide to not wear a helmet while hurling down the highway at 75mph. which one’s more likely to get me killed? And, if I choose to get up during turbulence and am injured I do not have a right to sue the airline for damages.
Unless there’s a last minute extended delay it’s about 10-15 minutes before the plane lands once flight attendants are told to be seated for landing. You mean people can’t think to go beforehand or hold it in for 15 minutes?
Mid flight might be a bit different. At some point if the seat belt sign is on for an extended amount well mother nature.
The problem is if someone chooses to get up it isn’t just themselves they are endangering.. it is the person or persons nearby they will injure when they fall on them.
