FR has also said that it will never operate flights to/from Heathrow, Paris De Gaulle and Frankfurt.
That is believable: too many delays at Heathrow, both landing and takeoff; taxi times are too long; 25 minute turnarounds are not possible; no dedicated "no frills" terminal; contact gates have to be used (mostly).
Doesn't fit the FR model: FR doesn't make money with its aircraft stuck on the ground, so don't believe it for a minute.
FR spoke about it this week and would consider it. They have previously said a lot of things they would never do and are doing them!
As for turnaround etc, 25 minutes has turned in 35 minutes for many routes and if EI have a reasonable good OTP then FR could have the same and they only allow 40. On their DUB-BRU route they have a 70 minute turnaround in the mornings for slot reasons. Don't see them dropped that any time soon...
