It really is quite simple. Book your flight. Wear a mask for the duration of the flight. Refuse to wear a mask, and you’ll be banned indefinitely from flying with Delta Air Lines in the future.

The Atlanta-based carrier has been very clear about its policy since the onset of the COVID-19 pandemic, but inexplicably there are people who refuse to abide by this no-brainer requirement.
In fact, if you haven’t flown since the coronavirus arrived in the U.S., you should know that ALL U.S. airlines require a face covering for ALL passengers in the boarding area, during boarding and throughout each flight. Additionally, most airports across the country require that a mask be worn by everyone inside the airport terminal at all times, with the only exceptions being while eating or consuming a beverage, or if a verifiable medical condition precludes you from wearing one.
In a concerted effort to show that they mean business, Delta announced in July that 120 people had been placed on its no-fly list for refusing to comply with the mask requirement. The list was expanded to include a total of 240 customers as of August 27. And now, 220 additional fliers were added to the no-fly list, for a total of 460.
United Airlines has placed more than 300 travelers on its no-fly list, while Alaska Airlines reported 146 customers also on its list for refusing to wear a mask inflight. American, Southwest and JetBlue have not made this information public.
With the U.S. now experiencing its third and worst spike in virus cases, it is abundantly clear that wearing a mask, washing your hands, not congregating in groups and maintaining a safe social distance of at least six feet will be the minimum necessary for the country to get a handle on the spread of COVID-19.
