When I get to the Passenger Information page, there is no pulldown of travelers. When I fill out my information (FF # included) and proceed to the seat selection page, all of the stretch seating is blocked, as if it doesn't know who I really am any more (or at least that I'm Summit).

I see this in SeaMonkey (a Mozilla derivitive) and Internet Exploder.

Anyone else having problems like this when booking tickets?
