The pain is pretty equally shared. The Airbus fleet is short of pilots at the moment, the 777 is doing more ultra long haul, now with 3 crew not 4.
90 hours is typical of every month at the moment. The problem is not the number of trips (3 or 4 layovers is not too bad) but the number of night turns, especially to India. If the flying were pure long haul it would be better but once you get to about 90 hours they can still fit in a couple of short turns (2 hours block time) to take you right up to 99 hours in 28 days, or 900 in a year.
Minimum legal days off and 99hrs 59 minutes in 28 days seems to be the target at the moment.
In about 7 years here I've never been so tired.
