LCA and ZTH are (I hope) a given, just unfortunate it'll be 2015 and not 2014.
I think that by the end of 2014 one (or hopefully more) of the following will be announced:
Wizzair: Maybe Warsaw, Gdansk, Poznan etc... (x2-4 weekly, A320)
Vueling: Barcelona (x3 weekly A320)
Turkish: Istanbul (x4-5 weekly 739)
Then there are some that might happen later, 2-3 years time, if we are lucky, but I wouldn't get my hopes up:
SAS: Oslo and or Bergen (x4-5 weeky 736/CR9)
On the other hand there are the ones with potential that unfortunately will never happen due to various factors:
El Al: Tel Aviv (x2 weekly 737/738)
I'd be quite condifent of BUD from LS too.
Dare I say New York might happen in the next 20 years?
Cheers, some speculation for the new year. I've heard that Wizzair have considered NCL before and Vueling, so I heard, was almost confirmed but maybe not. Turkish are expanding very rapidly, SAS? Norway used to be strong, times change? Bergen Maybe? El AL, there are lots of orthodox Jews in Gateshead, the largest outside of Jerusalem and many will only fly EL Al so there is the possibility, but Newcastle might not be complient, I don't know.
