I'm prepping to book my first international flight and I would appreciate some guidance regarding the layover, if someone can help me. The flight I'm looking at is Denver, Colorado, to Shannon, Ireland. What I'm looking at is Continental from Denver to London, with a 2 1/2 hour layover, Aer Lingus London to Shannon. This would be on one ticket, I believe, as it's the option that comes up for me, not two separate searches. My question is - on such a flight, would I have to pick up my luggage in London and re-check it for the flight to Shannon? The info on the Continental website doesn't seem clear to me, I'm sure because I'm new to this. Thanks in advance for your help!! Oh, and is it safe to assume the 2 1/2 hours will be long enough to make the connecting flight seeing as that's how the potential booking comes up on inquiry?
