I have a newbie/dummy question. We're leaving tomorrow for Ireland and have a Delta positioning flight to BOS and then an award booking on Aer Lingus from BOS-DUB: itineraries are not linked. We aren't checking bags, so was thinking we wouldn't have to go thru security again. But do I still need to check in with Aer Lingus' desk or can we just check in online tonight and then go direct to the Aer Lingus gate?
We did the same route last year, but we stayed overnight in BOS so we went thru security and checked in with AL on the date we left the US.
