I have to say that I think there is some mass reworking of flights with Easyjet at the moment. At Basel we have flights to Liverpool only once a week when before it was almost daily, and London Luton and Stansted are gone - hopefully only for the moment, with only London Gatwick available twice daily at businessmen times and fares ..........
I'm flying GVA-LTN in June and there were still a choice of daily flights when I booked and paid in March ........................
