Does look as though BFS may be in the running although it is likely Jet 2 will have their work cut out - last time LBA was served from BFS was a few years ago until Air UK transferred to BHD and then discontinued the route after Flybe started. Flybe have operated the route since then without competition and will do whatever they have to to maintain their market share.
Also, Jet 2 will face the wrath of Easyjet at BFS. Good luck to them they'll need it!
