Most people would think that after being away for several days the cabin crew would want to get back to their homes/loved ones rather than wanting to stay in a hotel for another 2 nights not so far from home base.
I am not convinced this is what some of cabin crew members really want.
I agree with deecee3 that getting the customer to their destination should be the priority providing of course it is safe and legal to do so.
I am not convinced the new rule of only 1 night at diversion airport will achieve a great deal financially because the pax's will still be left somewhere they probably do not want to be. I fully understand that after a long range sector there may be no alternatives other than getting a replacement crew positioned out to take over but that is probably very difficult or impossible.
If an aircraft diverts to another country close to the UK will they still need 2 nights off instead of just one or the 13.5 hours someone mentioned?
