Folks:
This is obviously a new issue for those of us who fly DL mostly, as Heathrow is a new destination for DL. I just scored two Skysaver tickets today to London/Heathrow (YES, it still can be done), and plan to connect on a BA flight to the south of France. As a DL captive, almost all of my prior flights to London have been via LGW, so I'm not really familiar with the connection times, and challenges, at LHR.
My itinerary has my wife and me landing in LHR at 9:00 a.m in late September, on a flight out of JFK. We have two choices for a connecting flight on BA to NCE: one leaving an hour and 40 minutes after our scheduled landing at LHR, and another one leaving 2 and a half hours after landing.
My conservative instincts tell me I should book the later connection flight, but I would welcome everyone's input. I am particularly interested in any information concerning where, in Heathrow, the DL flights from JFK and ATL are anticipated to park, and the proximity of those gates to the intra-European BA flights.
Thanks to all.
