When one of your passengers is kicked off a flight or glued to their chair, maybe after refusing to wear a mask or hitting a flight attendant, do you tell anyone? Delta wants airlines to share their lists and has admitted it has 1,600 people on its incidental no-fly list. But others are not so keen to admit the magnitude of the problem.

Airlines’ banned passenger lists are separate from the federal no-fly list, which is maintained by the Terrorist Screening Center of the Federal Bureau of Investigation.

American Airlines and Southwest Airlines currently do not sell alcohol on board due to concerns about how alcohol consumption could fuel bad behavior.

New Southwest CEO Bob Jordan told CNBC on Thursday that he did not expect alcohol sales to return until the federal mask mandate for air travel was lifted, a step currently scheduled for the January 19.

Representative Peter DeFazio, (D-Ore.) Chairman of the House Committee on Transportation and Infrastructure, said Thursday that airport restaurants should help prevent passengers from bringing alcohol on board with take away cups.

It’s fun to see how each source has their own magical thought about why people misbehave on flights, like we invented alcohol and started drinking last April.

It also looks like a classic battle between lawyers and public relations, playing out differently between different airlines. Lawyers usually win, even when running the business off a cliff, because of the sunk cost error. The hill you buy is the hill you die on. But constantly kneeling down by other priorities can be overwhelming. Delta’s 1,600-person list suggests multiple daily incidents serious enough to warrant arrests, landings and detours. That’s a lot of duct tape!
