Crew rest
Pilots of long haul carriers require and deserve the best rest they can get and that means a dedicated crew rest containing a comfortable bed and a room wich is quite and separate from passengers and noisy galleys. Anything else just not acceptable. This should be mandatory and up to the respective CAA's to enforce for safety and not up to airline's to use as a negotiating tool or cost saving issue.
The airline I work for has a dedicated bunk which is acceptable. Unfortunately on one of our aircraft type they have a crew rest (Bunk?) which is pathetic, situated at the rear galley in probably the worst position next to the toilets and galleys with little privacy from the pax. In this case the carrier makes available a first class seat - but even that is not really acceptable as it is not possible to have an un - interrupted rest.
The dedicated crew rest or bunk should be the only acceptable rest area and we should not be accepting anything else.
