Airbus Girl
I work for BA and have done Tel Aviv there and back in a day on both the 737 and 777.
The 737 was a scheduled day trip (40 min turnround) but often we had to divert on the way home as even with discretion we were out of hours. It happened so often that the company saw sense and moved it to 75/6 and then 777.
On the 777 I have to admit we did carry an extra heavy pilot as again the duty day exceeded limits with 2 crew. Remember you cant turn around a 777 in less than about 2 hrs if its a full one rather than a transit.
One of our aism is to provide a robust operation for our premium passengers and a reliable sceduled service is what they pay a premium for. Delaying/diverting/cancelling flights due to crew hour problems is not acceptable. Yes other crews do work harder than us in certain areas but OUR pax pay for increased reliability of the schedule by having crews able to complete sectors even after delays.
Not having a go....
