What is the longest period of time a flight crew or FA's ban pax from useing the LAV, Iv never been told that I could not use the lav' even when the seatbelt light was on, but I here storys from people that have been told no. So whats the deal, anyone one ever been told no?
Technically, we can't 'ban' anyone from doing anything. You have to have authority to do that. We have responsibility, but no authority. For instance, if you are caught smoking in the lavatory, I have the responsibility to ask you to extinguish your cigarette and to report the incident but I have no authority to detain you or mete out any kind of punishment. The captain has authority but not really the cabin crew. It is kinda like the difference between a shopping mall rent-a-cop and an actual police officer.
What I always tell people is the I am responsible for telling them that while the seat belt sign is on it is SAFEST
for them to remain seated. Beyond that they are on their own. I have done my job and covered myself. People often will ring their call button and ask "permission" to get up while the seatbelt sign is on. I always tell them that asking a flight attendant if it is okay to disregard the seatbelt sign is like asking a cop if it is okay to speed. We always have to say "No" but that does not mean we don't understand that their are times when the rules have to be bent.
It never hurts to ask the flight attendants if the captain could turn off the seatbelt sign. Sometimes the flight deck thinks that leaving the seatbelt on is a courtesy to the cabin crew who is trying to complete a service. Other times, they just plain forget. The worst they can do when we call is say "no".
