Yep, as I noted. BA1 if connecting to an onward flight at T7 would work.
What is the DFW "airside post security connection route"?
Skylink
http://en.wikipedia.org/wiki/DFW_Skylink. Means you can move airside between terminals at DFW without having to go through security again. My thought was if there was a pre-cleared flight coming in to DFW do you come out in to the airside departures area (like BA1 at JFK T7)? So would you be able to go to another temrinal at DFW via skylink and then get on another flight (INT or DOM) without passing through security at DFW?
