Airport twitter feed is saying: "Additional destinations to be announced soon"
Loganair are shuffling around their summer 2022 timetable right now. Currently Heathrow is only twice daily (although currently the plane is timetabled to sit on the ground for 1h 40 mins at LHR) and no sign of Jersey or Bristol at the moment (I would be shocked if Jersey did not appear).
So there are two early afternoon gaps in the schedule right now. One might still be for Bristol (plane that goes to Aberdeen) but anyone care to speculate about other destinations?
