Ireland is among the world's largest exporters of pharmaceuticals and
computer software (and there's hardware too) . Yes, there is drink, of
course, but part of Ireland's economic boom has been built on exports. Sure, there's not much in the way of heavy industry, but exports are quite significant and of course, the airline that can tap into this market can also carry it on to other major markets across Asia.
The only concern I have is that with a pretty short runway (8,650'),
you're not going to be able to use the 744F to its full advantage; at
max payload, you're probably only talking about 5-6h out of Dublin.
Don't know if CX has a minimum runway length for 744F ops? (or KA, for
that matter?)
