Air Canada flight attendants are entitled to 2 hours sleep on non-stop flights over 11:30 (any flight under that time the flight attendants have no special arrangement). On AC
's A340-300 a mobile crew lounge is boarded in the baggage hold below deck. It is mobile because it is only loaded onto the aircraft on flights that are above 11:30 hours in length.
A locked door between the two main Economy cabins leads to a steep staircase into the lounge. When the lounge is not on board there is a trap door that closes over the staircase opening. In the lounge which is basically two baggage carriers joined together, there are 6 beds with individual air vents and reading lights and privacy curtains.
