Re the competition - surely the competition is who the airport will want to attract - so a TUI/Jet2/Thomas Cook or such like aircraft being redeployed from Newcastle or Leeds to be based here to satisfy the local demand - there isn't anyone that doesn't already serve Newcastle or Leeds that would fly from here, is there?
What else could there be? - Loganair Carlisle - Durham - Southend?
Back to the here and now - Eastern/Flybe Aberdeen, down to 2 flights a day Mon-Thu, and 1 flight on a Friday. Sunday flight looks to be on a based J41, up until the end of March 2019 (Humberside the same but not on a J41? and they lose the Sunday, but Newcastle who have historically been carrying a lot less passengers than both here and Humberside, keep the 3 flights a day)
