There are two routes I'd love to see into Newcastle; a Cancun flight and a New York scheduled flight. These are two routes I use all the time for holidays and am sick of having to travel to a far away airport or increase the travel time/reduce holiday time by making connections.
Newcastle is fine for Sanford, but anywhere else long haul - its not so good.
Bring in Continental into Newark as was rumoured a couple of years ago and I'm sure NCL could support a CUN flight on a 763. I'd even accept a 752 Newark flight; anything to start using the local airports more.
