Except that in the US (unless you are at the airline's home base) the checkin+gate staff are probably on contract from some staffing agency or rented from the airport.

The 'Delta connection' flight you are on is sub-contracted out to a 2 man outfit with a single regional jet.

Pay and conditions are so poor that staff turnover is huge and the number of staff is reduced so that people barely have time to glance at the person.

It's one of the hidden costs of replacing the company security guard with the cheap outside agency.
