Hello.
I know AA uses the E satellite and other high E gates at DFW.
However, I was surprised to see this:
AA2567/14DEC
DFW 630P E E7
BOS 1 B12 1058P
Does AA really use E7 at DFW?

I thought this was NK/AS/DL or UA. I checked and got this reply.
Terminal E at DFW is used by a variety of domestic carriers — for example, United Airlines, Delta Air Lines, Frontier, JetBlue, Spirit Airlines, Breeze Airways, Alaska Airlines, and others operate flights from E gates.
