Dont know about Gander but I am sure that there are a lot of Newfoundlanders that would be more than happy about a three or four weekly flight from Stansted to St Johns? I bet the Newfoundland government would be more than happy to provide some incentive funds to re-establish a St Johns - London flight in the wake of the departure of the short lived Air Canada A319 service from a few years ago and preceding that the 767 service. There must be a reasonable market there as even I know a person whom was a regular on that flight down the years.
Would be worth a punt over the course of a summer season to see if it would work so how about it? If we ask Leo nicely he might be good enough to say to it Michael?
