I can picture readers on this forum based in the UK looking at €2,000 trans-Atlantic J fares and asking how it’s possible for them to ever be so low.

I’ve only recently started taking flights out of DUB, but I was able to pick up a flight from Dublin with an overnight in New York and then onto the Caribbean via Miami for just €2K. That’s not something you’ll be getting from any other European city that I’m aware of.
