I think anyone bringing a suitcase or two back from a day trip to NY would certainly attract the attention of customs....
We’ve seen how thin their margins are ex DUB from that chart the released a month or so ago, something like €3 per passenger. If the can get more people to take more bags and spend more cash then it could work very nicely, especially eastbound.

Edit, they’re actually losing €4 per passenger ex DUB, but they’re new markets.
