I fly on AA (and generally am upgraded, so I'm in the first few rows). On many flights, a FA has announced (on the PA), that there are several pax who have close connections, and to let them deplane first. I wait to see that these pax are heading down the aisle--but this never seems to be the case; perhaps other pax (from the rear of the plane) did not let them through, so after waiting a reasonable amount of time deplane as usual. Where were these close connectors?
