What is the crew rest area like on 747's and A340's? Ive always wondered!
GJ basically spelled it out. Search over at airliners.net for more pictures.
On smaller planes (767, 757, 737, A319/320) airlines mainly use an allocation of seats the most forward cabin. These seats normally have a device to limit light in that area.
United uses a First Suite on their 777s where other airlines have the rest area slightly above and behind the flight deck on the 777. I like this as th flight crew is in a confined area without the need to risk of opening the flight deck door. On United (777s) and Air New Zealand (747s and maybe others) they have seats in the Y cabin for rest.
Rest areas normally are in areas that could be used for cargo. If airlines can't sell the space for cargo or have weight restrictions on their routes then the cabin comes the rest area. It is a business.
