I would give Maersk Air UK or whatever they are calling themselves a pretty wide berth as they have continually let many people down by cancelling charters after committing to them and therefore have proved themselves unreliable. They only have Embraers or CRJ's now after disposing of their larger aircraft. I understand that the previous man in charge of charters was pretty fed up with the set up there and was glad to be out! Maybe they no longer do charters?
