I think the DAA would welcome anything with wings that could carry passengers at the moment, no matter how outlandish a scheme or daft an idea. They couldnt be in any more serious a postion regarding passenger numbers if they tried.
If they needed to stick a steam catapult down RWY 28 to get an airplane in the sky they would give it a go.
Desperate times mean daft decssions!!!
So far i have now heard on here, from DAA staff, Airline reps, pilots and guys having a smoke outside the terminal the following airlines ALL meant to be pre-clearing or tech stopping in DUB !!
Czech Airlines
Air Baltic RIX-DUB-JFK-DUB-RIX
Oman Air
Cyprus Airways LCA-DUB-YYZ-DUB-LCA
Air India Everywhere in India-DUB-The states
Singapore Airlines
Aeroflot
Manx2.com
Virgin Atlantic
Arik
Just to name a few i can spell without going on wiki, so really you could pick any one of the above and therorise for years but until the Airline says what its doing, i think in essense we are all taking crap, but very very interesting crap
