On a flight I was on several years ago (SWA) as we were disembarking several yutes from the back of the plane came busting down the aisle in a similar fashion as this fabulous fellow. When the line began to clear out from my row I stepped into the aisle and looked directly at the last of the yutes busting down the aisle. They stopped in their tracks and kindly let me disembark. I am no tough guy, just an average sized man who waited my turn.
SWA is allowing them to board as People with Disabilities the Old Blue Card system. Most of them have high B or C boarding numbers - it is ruining the system
I did the same thing on a recent flight. One got by me, but I was able to stop his friends.
I am an old woman who needs to lose 20 pounds, but I decided I was not going to let them get away with it.
