I'd be delighted to spill the beans about the
best ones I've had, and why- great crews (incl, of course, CC), communicative, interested, educational value.......etc etc.
Then again, I suppose its like newspapers- bad news sells, and good news doesn't- no-ones interested in the success stories.
I've only ever had one bad experience -terrible it was- asked at the end of the flight for a look up front, and the crew said 'Why didn't you ask before T/O? We'd have had you up for the whole flight'- I was devastated- and never made that mistake again!
Apart from that, I wouldn't tell if I had a truely bad one- everyone has a bad day, and as Niknak says, it is (was
) a privilege.
