More Ryanair?
I gather that the airline can base more aircraft at Luton but they have to pay the going rate as they got a deal with the airport to base four aircraft there. Also you will notice that on certain days in November and early December some of their flights do not operate to Nimes, etc. guessing that this is due to the 900 hour flight deck rule. I suppose they will come up with some other excuse!
I would think the airport authorities are reasonably happy at the moment with the number of new services being operated this winter but they must not rest on their laurels.
