Thanks Capt Chambo,
My question was the result of reading a US forum and that particular question was asked with that precise answer given.
However, at my airline we don't do that. Leaves me a little mystified because it is a reputable airline and I can't image I'm the first with that question.
I guess my next move is to send an email to flight tech on this but I'm a little afraid of asking a dumb question so that's why I wanted to get some feedback on here.
Thanks once again.
