Here's the ACTUAL wording from the Hotel Contracts Agreement:-
Where the Hotel wishes to upgrade Crew Members to superior rooms, (in addition to the Captain, and/or any specified in the agreement), such upgrades shall be allocated in the order of, Senior First Officers; First Officers; Cabin Service Directors and Pursers. Any room upgrade shall be at no extra charge to BA Group.
BASSA's "interpretation" is wrong.
Be careful out there.
