The 757 was always the plan to feed the Swefly.
I think the 767 would be more suited to this flight and during July I think will prove the worth of Leeds and hopefully they will then continue with the 767.
The great circle route (Shortest Distance) to Lahore goes overhead Stockholm NYO so landing there to refuel is an ideal plan.
I am sure other routes from Leeds via Stockholm are on the drawing board.
As for the Swedish crew issues they don't have any issues.
Swefly are a great company to work for, and the flight time limitations is not an issue for direct flights with a fuel stop.
Lets hope Swefly can help LBA hit 3,000,000
