All major US airlines began requiring all passengers over the age of 2 to wear masks while on board since the start of the pandemic. Exclusions include drinking, eating, or taking medicine. Hundreds of passengers have been put on a “no fly list” within the airline companies for refusing to wear a mask. One of those men was the ex-Nacy SEAL who killed Osama bin Laden who orchestrated the 9/11 terrorist attacks. The following airlines have banned dozens of passengers — Delta: 270; United Airlines: 150; Spirit Airlines: 128; Frontier Airlines: 106; Hawaiian Airlines: 6; and Alaska Airlines: 78. However, the total could be higher as American Airlines and Southwest Airlines have not disclosed how many bans they’ve issued. There is the potential of passengers being denied by more than one airline because the companies are not sharing names of the people banned. It is unknown how long the bans could last but is more than likely dependent on the individual’s behavior. Delta said that in some cases a ban could last for the rest of their life.
