So Aer Lingus should be able to operate BFS-Turkey
Even if they are allowed to fly between BFS - Turkey it's not going to happen in the near future. DUB will get flights before BFS.
It will most lightly be Jet2 who would fly between BFS - Turkey but they need more B757's to do so.
As EZY can't operate a A319 (full) to Malta and they don't seem to want to base a A320 in BFS. If they did base a A320 they could do a lot more longer range routes and there would be high demand for them.
