The A330 is very loud in the back; better to book a forward seat.

Check your bags if traveling to the US if included / possible. It was a long walk for the flight connection and we did US customs and immigration in Dublin, not Boston, which was a first for us.
YaneliFlew with Aer Lingus-Apr 2025
Arrive early (3 hours) because lunes get very busy.
