On: Man creatively sneaks onto Delta flight, but gets ...

It's not like the plane is going to leave earlier if the queue is processed faster.

Experience says otherwise; I routinely take use domestic flights that leave the gate early and take off early because they finished boarding early.

Maybe so, but that has nothing to do with the gate check-in.

The bottleneck is at boarding the plane and seating. Passengers stand in line on the jetway after they check in at the gate. The only reason gatecheck is rushed is to reduce amount of staff-time required at the airport. It doesn't get the plane boarded more quickly.

In Turkey, they are explicitly disallowed to do so, and has been the case even before 9/11, due to how Turkish transport licensure system works.
