Does MF have to pay for your bar/DF/bunk keys, and if so how much.
No we don't. £0.00 for initial issue. Replacements for lost keys are chargeable, but if the bloke/lady behind the desk in CC Direct likes you - free replacements. So no change there!
Also are you being asked to close the doors behind you in T5 when leaving the a/c as they wont be sending ground staff down to your a/c on disembarkation.
True - to the extent that it's a "trial" which if "successful" will become the norm - whether it's MF-specific or potentially applicable to all fleets I don't know.
