Delta, Southwest, and American Airlines will not require employees to be vaccinated, per CNN.
United Airlines is requiring all workers to be vaccinated by October 25.
"We are strongly encouraging our team members to get vaccinated," American Airlines told Insider in a statement.
Southwest Airlines, American Airlines and Delta Air Lines will not require unvaccinated employees to receive a COVID-19 vaccine, according to CNN.
The airlines will not follow the likes of United Airlines, which became the first airline to mandate all workers to get vaccinated by October 25 or risk losing their jobs.
According to an internal memo reviewed by CNN, Southwest Airlines CEO Gary Kelly said the company will "continue to strongly encourage" that workers get inoculated, but will not require it.
"Obviously, I am very concerned about the latest Delta variant, and the effect on the health and safety of our employees and our operation, but nothing has changed," Kelly allegedly wrote.
"We are strongly encouraging our team members to get vaccinated, and we are offering an incentive for those who do. American Airlines team members who get vaccinated are provided an additional day off in 2022 and $50 through our employee recognition platform," American Airlines told Insider in a statement.
Insider has also reached out to Southwest and Delta for comment.
