Boarding lasts 20 minutes or so, if you’re in the gate area at the start of boarding and you have to ‘go’ you really should do it before getting on the plane.
Sneaking into the lav while passengers are trying to get down the aisle slows things down.
Sure, sometimes it’s necessary — maybe your inbound flight was late and you make it to your connecting gate just before they’re going to shut the doors and you have to go.
But here’s the risk. If you do it right before takeoff, and it takes you awhile. . .
A female passenger found herself trapped in the lavatory on board a British Airways plane as it hurtled down the runway and took off.
As the plane gathered speed the embarrassed young woman sheepishly stepped out of the toilet, only to be ordered back inside by a screaming air stewardess.
Moments later the packed Gatwick-bound flight took off – with the passenger still locked in the toilet without a seatbelt to anchor her to the lavatory.
The woman was only allowed to return to her seat after the flight was safely in the air and the seatbelt warning lights had been switched off.
The flight was from Amsterdam to London-Gatwick.
