There's not that many 30+ years Captains anymore, not that length of service is a measure of their character any more than the colour of their hair. Anyway, you need the old codgers to tell you where the cheap beer and food is.
Tours are good, Captains are generally good, cabin crew are generally best forgotten about, you'll rarely see them off the aircraft no matter how nice you are to them. There are plenty of ex easy chaps in BA, I'm sure one will be along shortly to give you a comparison but by and large we don't seem to hear too many complaints so it can't be that bad!
