Doncaster as has been stated has more check in desks than that.
To suggest no other flights this year makes me doubt your story - no offense, your blissfully unaware that the airport is not simply just for Airlines but handles a very interesting mix of cargo and private aviation .
Granted it is not as busy as other airports but then I can imagine you complaining if you had to endure Dublin airport, long walks to your gate expensive airport cafes etc.
But all par for the course when using ANY form of public transport.
