I have NEVER been to a toilet on a plane.......
Most of my air trips are only an hour and a half, the longest one was four or five hours.
I'm not getting my arse sucked out of no plane, thats for sure.....
I haven't used one since getting locked in one several years ago. Somehow the locked jammed and the door wouldn't open back up. It was a real big to do, with lots of people standing on the other side trying to figure out how to take the lock off, or flip it back up, whatever.
When they finally got me out, I sat embarrassed in my seat until we landed.
Never again! Never!
I only went in there to PEE for god sakes!
