Looking at the Jet2 aircraft based in ALC and PMI for Summer 2017 it seems there's one or two gaps in the schedule... Notably Monday mornings on the ALC based aircraft and both Thursday and Saturday afternoons/evenings on the PMI aircraft. I'm guessing these may be for STN flights?
Another thing also about today is it begs the question how long before a New York flight is confirmed? As brief a schedule it may be, I'm sure we'll be seeing these come Christmas 2017/18, but who knows there may even be a regular operator to New York by then?
I wonder if Jet2 could even announce this when they reveal their Summer 2017 destinations... when does Jet2 normally release Winter schedules?
