If the airlines were THAT bothered about Yorkshire then they would be flocking their in their hordes to serve any airport in Yorkshire. AA is using 757s to MAN, UA will be doing the same to NCL. What's preventing them doing the same to LBA - it's not as if a 757 can't operate to EWR as Jet2 do it at Christmas.
You are again spending money that no-one has in (a) developing Church Fenton to be better than LBA and (b) closing LBA down. After all, you are going to compensate all interested parties at LBA, aren't you?
