I will depend on if Icelandair get the right type of aircraft
The Dash is too small, slow and expensive for NCL-KEF, and the 757 is simply too big.
The 737MAX... Maybe, but still on the large side. I'm sure that if Icelandair had E-jets or Cseries, Newcastle would be one of the go to destinations
Ash666, our only option for a direct Thailand service is TUI on a 787. The 787 is the only one that can do 11 hours non-stop out of Newcastle
TUI do fortnightly flights to Orlando and Cancun from Newcastle, which I hope will increase to 2 weekly if growth continues. They all go out full as it is, and the ability of offering 10/11 night holidays alongside the current 7/14, could only be a good thing
I doubt I would trust WOW to stick out a full season, never mind year round
