Even debt free, what have SNN actually gained? FR replaced EIR on a few UK routes, the EI trials of CDG and FAO are gone. Other than a cargo service from TK, not a lot has been achieved.
If people are looking at facts, rather than political spin, separation makes no difference. The daa is an airport group, they should promoting and optimising all of their assets. Should Manchester Airports Group be split (MAN, STN, BOH and EMA)?
ORK needs to decide what can be realistically achieved. Interest from airlines other than EI and FR should be heavily encouraged, destinations in Italy, Germany, Switzerland possibly even Scandanavia are what ORK needs and don't overlap with SNN. An air service to DUB and possibly Belfast would be desirable. Transatlantic is off the table, at least until aircraft like the A321LR are in service.
