A BBC report suggest that KLM will add three more AMS routes from the UK in 2013, in addition to Manston already announced.
BBC News - Could airport hub capacity see UK lose out to rivals?
Any idea what those could be?
Largest markets (airport size-wise) not served by KLM are (thus not including secondary airport at cities already served):
Liverpool
Nottingham East Midlands
Belfast
Southampton
Doncaster
Exeter
Bournemouth
Southend
Inverness
Derry
Blackpool
Newquay
Of those, only Doncaster, Bournemouth, Derry, Blackpool and Newquay have no AMS link at this point, while the others are served either by Easyjet (LPL, BFS, SEN) or Flybe (EMA, SOU, EXT, INV).
Not sure if we can rule out LPL and SOU given that KLM axed an existing link not too long ago.
