Top stuff!
May I suggest the following embellishments?
...A lifejacket emblazoned with the logo of a designer that was fashionable five years ago, is located in a pocket beneath your seat. ChavAir are assured that these are the genuine article and not something that the Chief Of Operations scabbed off a mate, the last time he chucked a sickie to help empty a warehouse.
...You will find a flashlight and whistle attached to the lifejacket, so you can amuse yourselves by simulating a rave whilst awaiting rescue.
