In terms of Regional France, Bordeaux and Lyon are the now 2 obvious gaps, with Lyon previously managing up to 2 daily flights but now relagated to a meagre ski route status and nothing in the summer.
I also think Nice could manage more than 5 weekly flights.
Agreed though, this news has given a much needed boost to the this route area.
Charlie Cornish has recently changed tact, from saying that he considers Europe well served, to now putting in focus on building up the Eastern Europe portfolio and adding capacity on existing routes.
I know it's old ground, but, I think there could still be a market for Seville, Santiago, Podgorcia/Tivat, Bucharest and, one route that seems to get a lot of requests from the North West is Asturias.
