About every other time I go through DFW, AA arrives on time or early, only to pull up short of the gate. The pilot then tells the helpless passengers that the ground crew is not ready. I want to tell the flight attendants to call ahead next time so that they'll know we're coming. Very frustrating to be within sight of a connecting flight and still miss it.
Hope this doesn't happen to you, but don't be surprised if it does.
