It’s happened to us all: You’re on a plane, and the seatbelt sign is on—but you really, REALLY need to go to the bathroom. Obviously you’re not supposed to leave your seat until the sign is off. But is it actually illegal to go to the bathroom?
Technically, yes. By the letter and number of the law, in this case 14 CFR 121.317(f), itÂ’s illegal.
But in real life, thereÂ’s clearly some flexibility in how the rule is applied, since many of us have seen fellow passengers sneak off to a bathroom before the sign is off with no consequence. What follows is a guide to that gray area.
There are times when you absolutely should not ignore the seatbelt sign. Don’t get up if there’s obvious turbulence or if a pilot asks flight attendants to take a seat and prepare for a bumpy ride. And if your plane is taxiing, taking off, or landing, never, ever, remove your seatbelt or attempt to go to the bathroom. Most airline accidents happen during this critical phase of flight, and your actions may endanger everyone’s safety. This includes the time immediately before a landing begins—it’s possible that your overlong bathroom break could force the pilot to abort the approach. A useful rule of thumb: If you don’t see any flight attendants moving about the cabin, you shouldn’t be up either. Stay seated with your belt fastened.
But what if the seatbelt sign remains illuminated long after the plane has reached its cruising altitude? If you decide to risk a surreptitious mission to the lavatory, don’t ask a flight attendant for permission. The Federal Aviation Administration, or FAA, distinguishes between flight attendants’ duty to inform and their duty to enforce. In general, the FAA emphasizes what information flight attendants must provide to passengers about federal regulations and when they must provide it. But the FAA is much less prescriptive in describing how diligent flight attendants must be in enforcing regulations—they don’t require flight attendants, for example, to lock the lavatory door anytime the seatbelt sign is on. Because of these incongruous expectations, flight attendants have evolved a kind of “don’t ask, don’t tell” detente: It would be negligent for a flight attendant to grant you permission to use the bathroom if the seatbelt sign is illuminated, but many of them aren’t likely to stop you unless they judge the conditions to be truly unsafe
