Yes, it's hard to see where new routes would come from for next year, unless a new sun charter or something. Ryanair are not in the mood for expansion from Irish airports and I don't know where else flybe could successfully fly to from Knock. The transatlantic charters received far too much
PR and I would be amazed if they led to anything in the way of scheduled services. There's no hope of a route to Heathrow and no sign of anything to any of the other hub airports.
So, in short, sustaining and improving the loads on exiting routes will most likely be the aim in 2017. That's not necessarily a bad thing though as sustaining passenger numbers north of 700,000 would be a good short term achievement for the airport.
