Thanks everyone for the info! Since I suspect it would be an A to C transfer landside, I decided to play it safe (I know - you're thinking - where's the fun in that?) and go through IAD / UA instead. I get to spend 3 hours and get in at around 14:00 instead of 11:15, but I won't develop an ulcer in ATL.

Now, if someone could only explain to me why one ticket costs $2000 more than 2 for the identical itinerary, that would be (while definitely OT) cool.

In the words of the famous song: "Why can't we be friends?" and with that hope, I wish all my fellow FTers a happy, healthy and peaceful new year!
