The airlines weighed in after a Biden administration official said the Transportation Security Administration would no longer enforce the mask requirement while the White House reviewed the decision and determined whether it would appeal the ruling.

Hours after a federal judge struck down a nationwide mask requirement on airplanes, trains, buses and other public transportation on Monday, the country’s largest airlines said they would stop requiring masks, ending a practice that had been in place for most carriers for nearly two years.

Generally, the airlines said they would no longer require masks at airports and on flights within the United States, though several said they would still require them when flying into cities and countries where requirements were still in place. Some airports may continue to require masks, too.

Here’s what each of the major national airlines had to say.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
