Dear AA,
I appreciate all the good to great service over the years, so this is why, in the spirit of improving our relationship, I offer this constructive criticism:
For those unfamiliar with DFW, the gates are always related to the terminal. So the terminal being B and the gate starting with D, that’s a disconnect.
I figured it out, but only after asking a terminal B curbside bag fellow which was real, and the answer was that the Terminal B was incorrect, it was supposed to be D.
No harm, no foul. A learning experience. From a friend.
