EZY are allegedly operating a full pre-Covid schedule from early September. Fares are temptingly good...now, are they really going from 0 weekly to 13 weekly to AMS for example? My hunch is the cash generation option cited for why the 2021 schedule is on sale isn’t far off the mark. I’d be surprised if all the Sep flights take to the skies and that’s far more immediate.
As an aside my STN-AMS has been retimed and the schedule appears to all be operated from the AMS base whereas from what I can tell SEN-AMS is being operated from SEN.
