We're trying to lock down an October trip for 4 adults. Open jaw flying into Zurich and out of Rome. Our local airport is small. We have to connect at least once if flying anywhere other than DFW, ORD, CLT, ATL basically. I've considered driving to DFW but between driving/parking for 2 weeks/etc., there wasn't enough price difference to justify.
The flight I'm looking at outbound flies first into Charlotte and then to Philadelphia but from there is direct to Zurich at least. I know absolutely nothing about the PHL airport. The connection time is 1:15. Is this normally enough time to feel comfortable that luggage will make it off our CLT-PHL plane and on to the PHL-ZRH flight?
I'm also concerned because google flights says this CLT-PHL flight is "often" delayed 30+ minutes. Should we skip this itinerary for an option that allows for a longer connection time?
An alternate route has a 1 hour connection in CLT and 1:35 at Heathrow? Would we have to do anything at LHR except just walk to our next gate? We don't have to gather bags and go through customs and recheck bags, do we?
in short:
I guess, in general, how much connection time is recommended between flights, especially international? Especially with checked bags? (and in particular, at ORD, CLT, PHL?)
