It will all come down too how much it is going to be worth an airline to call into DUB and how much they can get in bribes I mean grants to put pax thru the CBP etc.
As time is ticking on one would think that airline would want to start announcing plans for post opening so that they can at least start selling seats/cargo space etc etc even if it is only a few seats or one or two pallet positions on an airacraft.
I am surprised the the DAA have not at least indicated that additional carriers may be at least thinking about DUB as an option?
