easyJet
Based on my analysis (comparing operations on a Monday in late June 2017 with late June this year) easyJet now have 140 daily flights using 21 aircraft in summer 2017, compared to 136 daily flights using 19 aircraft this summer.
Interestingly, easyJet's Canary Island routes from Luton (Tenerife, Lanzarote) are still not bookable beyond the end of June 2017, despite most of the rest of the schedule now bookable to end of October 2017. It doesn't make any sense to me that these new routes are ending, but curious why they are not bookable yet. I wonder if easyJet are hedging their bets in terms of Sharm el Sheikh being restored for winter 2017?
