Good morning! I'm going to Venice, Florence, and Rome (in that order) from 12/13-24. I would come back from Rome after Christmas buy my Mom would be very upset (although we both acknowledge anything can happen and I could be stuck in an airport). Regardless, I'm trying to decide which airline/itinerary to fly. I'll fly out of RDU and my preference is fly into Venice and out of Rome, rather than in/out of Rome (but I could be persuaded otherwise). Price is always a concern, of course, but so is peace of mind. Given last year's snowstorms and multiple cancellations, I'm nervous about flying Delta to VCE via JFK or returning by AA via ORD. Even though it's quite a bit more expensive, I'm leaning towards flying AA direct from RDU-LHR-VCE and FCO-LHR-RDU. Until they change terminals around, I'll have to go between terminals 1 and 3 and go through security again each time. I assume I'll have to go through customs too? There are more than 3 hours (but less than 4) between LHR-VCE and 2.5 hours between LHR-RDU on return. Delta offers the cheapest flight, so far, flying RDU-JFK-VCE and then FCO-ATL-RDU. The difference in cost is between $200-300, depending on which site I check. Any points to ponder to help me make my decision? Should I wait until later to make my reservations?
