Flights to Nice for this November have been culled also. Most midweek flights disappeared. So it's not just the flights beyond 3 months time where this is happening.That is a dramatic change to both flights and we’re all very unhappy.
Ryanair changed my flight times to two different locations this year. Like yourself the change was dramatic. We ended up having to use taxis for transfers and also staying an extra night in one location. We lost time and we lost money....I reckon nearly €300 between the two holidays.
If you are flying to Faro or Lisbon....Aer Lingus also have flights available. Have a look at TAP also.
