In front of, on and behind the American Airlines check-in counters at Miami Airport, passengers have had a wild brawl. Eyewitnesses filmed these and shared them on social media.

There was no danger to the airline's staff or other travelers as the dispute was obviously a "closed" dispute. Furthermore, the affected check-in counters were not manned. This should also explain why no security personnel intervened and the arguers at the end of the video parted almost in a conciliatory manner.
