Gotta disagree with you Jack...it is most certainly not common practice at most major international airlines. There may be the odd one that does it, but any that i've ever heard of had a proper crew lounge in the terminal, seperate from the passengers that included sofa's, TV's, cofee etc.
The new building across from ops is not a crew lounge, its a place to wait till the buses pick you up, and by no means "suitable accomodation" . I think i'll just hang out at home after checking in, takes me 10 min to get to work anyway.
