force crews on turn around flights to do customs and immigrations? Unheard of in Europe I reckon, at least I have never seen it happen anywhere, not even outside the EU proper. Transit is transit.
There is a lot to be said for it that one airline seems to be willing to stand up against this practice. Frankly, many airlines in Europe have accepted much to much stupidity and harassment of air crews in recent years.
What if ALL of the airlines would have reacted to overblown legal snafu's instead of just accepting them and continue as before? As for instance the general suspicion of every crew member to be a potential terrorist....
