Judging by the 'low' figures LS get on LBA with 2 returns per day, he could give it a go in time for the Christmas rush.
Think it was mentioned on the Jet2 thread a while back, that while Jet2 are increasingly going for more bucket and spade routes especially with jet2holidays, the BFS LBA and BFS BLK do make profit. As the sector lengths are so short, can also fit around the timetable of the sun flights and keep aircraft utilisation high.
BFS LBA flights are operated by a LBA based aircraft, though if you suggest LTN route this would need to be BFS based to get the early departure.
