This co-operation, if it turns out to be real, may well have come about due to the "air bridge" which AUR are operating between Guernsey & the IoM (both islands being covid free for a few months now). It might reflect some sort of gratitude to the airline on the part of Tynwald, or inter island co-operation. There has been a lot of travel between the 2 islands & it has fostered friendly (& sporting) relations between them, too. Don't run down AUR too much - it is not easy for them, even at the best of times ! If the Manx people & politicians want them to operate some routes on their behalf, good luck to them all. But, I can't see Gatwick working for them if EZY stay on the route.
