The airlines have seen all the negative coverage and won’t go through this again. I would go and expect this to be a routine thing...at least once a week in the US where you get told to exit the plane stand-by for two to three hours waiting on the ‘problem-child’ to come off, with their bags to be removed.
There needs to be a national listing that you get on after showing this childish behavior, and forbids you for three years from another flight.
Apparently the woman doesn’t realize that you get you bags back faster when checking at the gate (you just have to lug them farther to exit). It also sounds like it could have been worse since they mentioned that another passenger had a medical issue while waiting in the terminal. They could have had a nice stopover in Pitt or Philly to kill some additional time. Oh the joy of flying these days!
