United paranoia strikes again. Make sure you never yell 'boo' at a United FA....they might have a stroke.
There is no FAR. Period.
There is a security directive from the geniuses at the TSA that states on international flights, passengers should use the lav in their cabin - since we all know how the carnage of 9/11 was caused by international flights and terrorists only enter the US on international flights
It's really not a security issue, but a courtesy and privacy one. Y folks should not be coming into C or F to use the lavs which are set aside for premium cabin passengers.
When I'm flying in F, I don't like Y people coming into my cabin, and when I'm Y, I'd never think of walking forward to use the F lav or store my carry-ons in F like some people think they have the right to do
