I night-stop with my crew in Europe. Typically we have between 12 and 20 hours in any location. Given that, what would you do? All we do is have a discussion and the best idea wins. Last week for example we popped off to a supermarket and got ourselves a picnic. Sometimes we hire a car. We go out clubbing. We go for walks, hire bicycles, watch a flim, go to the pub or simply do nothing. There's no rank, just a group colleagues who will try and make the best use of the time we have down route.
ps. We are a smallish airline, 600 cabin crew, 500 pilots. Average age late 20's, early 30's (with a few really old ones).
