No one outside of Shannon gives a s*** about preclearance. American at Dublin don't even use it! It's not the selling point you lot think it is.
I'm referring to the new CBP, not the immigration clearance. The ability to fly into US domestic airports directly from SNN definitely presents some opportunities. It's up to the SAA now to try and attract some extra business, whether through corporate jets, transit traffic or new airline services. They can't stand by and expect the business to flock to them, that's not going to happen.
