I don't think there is (or ever has been) a scheduled A3 LCA-EDI. Maybe summer charters but nothing scheduled, although I opologise if I missed something.

In the last week A3 have flown three round trips LCA-EDI, three LCA-BHX, one LCA-BRS, four LCA-MAN and daily LCA-LHR. That isn't normal, even for peak summer season. These must be repatriation flights, although whether they are for Cypriots or British returning home I don't know - maybe some of each. Why would so many people need to move at once this far into the lockdown? Could it be something to do with the British military presence on Cyprus? Or have cruise ships been docking and unloading there?

The flight numbers vary between 49xx and 60xx. I believe 49xx is an ad-hoc flight and 60xx is repositioning empty so this may be a way to see which direction people are moving (mostly TO Cyprus although some use 49xx in both directions).
