The FTLs used to say two days off after a ULR. So when you came back from JFK and landed around 8pm you would have that day off PLUS two calendar days. The powers that be (we can change any rule we don't like) said the day you land in DXB counts as a rest day and we now only get one day off after the trip.
So we were on company time for 20 out of 24 hrs of the day but that counts as a day off? No wonder so many pilots are tired and feed up.
