London trips used to be 12 days .. Frankfurt trips 14 ... Back to the future.
I can't see 2 pilot being the go though.
- You cannot do 2 pilot LHR-DXB after a 39 hr slip - Sched rules would need to be changed for that to happen
- DXB-LHR up to 8.30 blocks - 10 hr duty. Very little leeway before duty extension needed - and certainly, where you land you stay - no ability to continue to destination.
However, it will become clear in a couple of weeks ....
