Despite the name I am ba eurofleet crew.... Been flying for ba for just over 3 years and can honestly say that 1 sector days are few and far between. Yes they do exist but it is not a day to day occurance. Same for flight crew!!! My last trip was a Prague nightstop. 2 day 6 sector trip (both nearly 12 hour days).
I dont want to make this a flight crew versus cabin crew thread but on this occasion the flight crew had done 1 sector out to Prague and had all day there.
It works both ways.
