Gate agents are asked to do more with less than ever before. During the pandemic, American moved to single agent boarding where narrowbody aircraft that are less than 80% full get just one gate agent rather than two. They have to make all of the announcements, deal with standbys and upgrades, check boarding passes at the gate, and also deal with gate checking bags. They’re supposed to do passenger breath checks, too?
And they’re going to get called in if the flight pushes back even one minute late. No time to notice if a passenger is high on meth!
