Just on the topic of the OnurAir not departing due to a crosswind limit...
These limits are set usually by the company (OnurAir) and not by the Airport, Runway length usually isnt a factor with crosswind limitations of the aircraft neither is the weight of the aircraft, as a line pilot usually the only reason bags are offloaded is because the aircraft is too heavy to depart or too heavy to land at the other side, with the aircraft being above the MLW (max landing weight), however being a ORK based line pilot I agree that ORK is usually avoided in the event of a diversion due to the runway being slightly too short for comfort in the event of a problem, with SNN not that far away and a runway thats alot longer usually its a more sensible option!
