Hmmm... FlyBe with their low-cost model @ LCY. Can't see it myself. But aviation is a funny old place sometimes.
Thing is, flybe aren't really low cost, in that the costs of their tickets are, well ....high. They do have a loooooong history of losing money at LCY as Jersey European though, so if they want to serve London, and that's a big if given the deferment of the ERJ-170s, it's LTN or STN. Yeah.....
