Abu Dhabi - given the success of EY and EK out of DUB maybe this is possible from BFS, but would EY realistically operate from both airports or is it that they are looking to decamp to BFS and let EK take over at DUB? Interesting.
Not a chance of them leaving DUB. If they did they would be closing there maintance base and lose a good customer base. Quiet a lot of people feel that it will be upgraded to a B777 at some time in the short term and then EY have already confirmed plans to fly there B787 from 2014.
If they start BFS it will most lightly be A330 at 4 weekly like they did when they started at DUB. There is room for both airports but DUB will win hands down on price which may still draw passengers from NI to DUB.
TBH I don't see BFS happening but you never know...Canada has a higher chance in my book.
