I have booked a flight for Dec on this route- I just want to ask about check in. It says the Dublin to Boston route is operated by ' Air Contactors' for aer lingus. I wonder if it is United or KLM or similar.
With that in mind, do we check in at Heathrow with the usual 3hours or so for economy transatlantic? I have been looking on aer lingus website but not sure of the answer.
Many thanks if you can help
