I think that CPT is already covered by GSM, but competition never heart anybody (except Mytravelite!
)
I think that all these long haul destinations would only come about from it's new base if the short haul flights were to prove themselves. No good sending 2 or 3 A330s to a base that can't fill a A320!
Would love it to be MAN, which would give it a real boost and help it's quest to regain 3rd busiest airport and push for 2nd. Afterall, MAN is wanting to be the 2nd biggest by 2020!
