Clearing US immigration in DUB sounds very attractive, it's supposed to be a real pain In US.
Yes but is it worse than the pain of rubbish DUB timings on connections from NCL?, EI don't market NCL-NYC as they can't do a through route without a night stopover. So you look at a Loco, then at best you have to hope they run to time, and then allow enough time to pick up & drop off baggage. Unfortunately at this time all of this far outweighs the percieved advance US authority clearance at DUB
