45 minutes at DFW? Are they serious? This is an airport that was designed for O&D travel, with minimal distance from the ticket counter to the plane (excluding AA obviously). How many gates does US use at DFW? Three?
Lord help us, if US can't load a bag at DFW in 35 minutes, how do they manage at BUF or ILM?
It's a fact homey, TSA only has one station to scan bags and then get them back to the airline.
FYI, four gates. East and West.
