Back in the late 90's while studying for my ATPL's, I had my TAFE instructor write a letter to Qantas, just prior to a holiday I was taking to Singapore.
Ended up being invited to ride the jump seat from departure the whole way through to arrival in Changi. Got the same courtesy on the way back to Australia. It was like a dream come true for a fledgling pilot
Its a shame terrorism & security measures post 9-11 have ruined the ability for crew to invite passengers to ride the jump seat these days
