I was lucky enough to be allowed to ride the whole flight from take-off to landing on the jump seat of a Ryanair 732 recently.
It happened to be one of the hosties birthday. Half way through the flight, at the end of the usual update PA, the Captain added, "and I'd also like to wish Sarah in the cabin a very happy birthday after her 35 very youthful looking years.
With that the flight deck door nearly came off its hinges being pulled open so quick, and a very mean looking face was thrust through. It was her 25th birthday!
