After banning over 1,600 people, Delta wants airlines to work together to keep unruly passengers off their planes.
The airline is calling on other companies to share their no fly lists because as a Delta official said:
"A list of banned customers doesn't work as well if that customer can fly with another airline."
The FAA has reported more than 4,300 incidents of unruly behavior by passengers - many of which involve disputes over facemasks.
