If it helps, I booked with them when they initially tried to start up. IOM-MAN. Just one pair of flights. When it didn't happen, they were quite prompt in issuing a full refund. No problem at all.
The Island really does need to drop the Open Skies model. With U2 offering MAN flights daily for three days a week imminent, it will no doubt ruin the Loganair product and lead to no IOM-MAN flights some days or at weekends. EasyJet and an Island that needs frequency and guaranteed service are not a good mix!
Good luck to anyone helping to knock certain politicians into the real world.
