My favorite people watching is a gate and terminal change at DFW on an already delayed flight. It is hilarious to watch neophyte passengers on the run from the old gate to the new one. It's like watching an episode of the Amazing Race. They jog to get to the escalator and then decide to run the stairs to beat the line for the escalator all the while carrying their multiple 50 pound carry-on bags. Once they get to skylink they stake out their acreage with their elbows until they get pushed further and further back in the train wedged like a sardine. Elbows firmly pinned against themselves and realizing they will now be they last to get out of the train car. Funny how it takes 30 minutes to load a plane but a skylink train can be loaded with a full MD-80 passenger load in just 3 minutes. The existing train riders are stunned as if they are witnessing a flash mob. When the train arrives it is like they have opened the gates in Pamplona for the running of the bulls. People rush out looking back at their competition looking for an edge. Do I go right or left to get to the gate. Do I take the escalator, stairs, elevator. I literally see roller-boards lift off their wheels and become airborne. Now it gets serious as the mob sees the new gate and the fast walkers are now more of a jog. Those passengers with roller-boards are at a severe disadvantage as they are being held back by their luggage that just wont roll any faster. People cut through other gate areas or behind a row of chairs for a 3 second edge to arrive first at the gate. A startled GA looks up as people are catching their breath and announces it will be 30 minutes until we board as we are awaiting aircraft from the hanger. A big sigh from the group as they are now dropping their baggage to the ground strategically placed to protect their new real-estate. Elbows back up as well. About 10 minutes later the flight crew arrives snaking their way to the front of the line chuckling along the way as to what they just witnessed and cracking jokes as they wait for the plane to arrive. It gets better as the GA is frustrated she cant get to her multiple wheel chairs pre-boarded and has everyone clear a line from left of the priority boarding sign.
