Any ideas how the extra DUB-JFK is selling? I'd expect the early departure from Dublin is popular, but the return will probably struggle!
With the aircraft in Dublin from its arrival at 23.40 until departure the next morning, I wonder would EI consider having the aircraft sit in JFK for a few hours, and have the departure around 19.00? That would stagger the JFK-DUB flights to being at 17.30, approx 19.00 and 21.30?
