We are flying from Chicago to LHR, arriving at 10 a.m. on a Saturday. Our connecting flight to Salzburg is out of LGW at 1:25 p.m. The American Airlines agent I booked the itinerary with assured me that the transfer time is within the airline's allowable guidelines. To me, it looks crazy.
For the pros: The tickets were $1000 less for each of us than our next choice (they're business class tickets); we'll be among the first wave of people off of the plane; our three flights were booked on one itinerary; and, because I had a voucher to use, I used a live person at American to make the reservation and she assured me this is doable.
For the cons: It's LHR, where we've been in lines so long that carts were brought around with complimentary bottles of water and snacks.
It appears to me that our choices will be a National Express bus or a taxi. I'd love to hear from someone who has had personal experience with this.
