Can't see the Londonderry-Belfast routing being a great problem to them.
That gives me an idea...
LTN/LGW/STN -> BFS -> LDY
The first two stop EZY service? That would certainly give the Airporter bus a run for it's money
They're going to have to do something about the train line at the western end of the runway as well. If the controllers think that a train is in the area, but can't see it, any aeroplane on the approach has to go around and hold (or begin again).
If you can't see an NIR train crawling along the coastal line, you can usually see the plume of black smoke, or maybe hear the monstrous noise... Incidentally, Castlerock to Derry is one of *the* most beautiful rail routes in the UK and Ireland, and with forty year old railcars still running for a little while yet, it's practically a preserved railway...
