cuthere,
Well if someone asked me, while on a flight, if I was happy to land at the airport where I had booked a flight too then my answer would be yes!! So I feel that you are suggesting a preference.
By the way, I most definitely support one airport for NI, and find the current situation is costing opportunities, jobs etc as the 2 Belfast airports fight it out. The real winner is Dublin and many, not just me, see this as the reality. Until either there is one owner of both or authority step in, this will continue to be the case with no advantage to NI plc.
