(CNN) — United Airways CEO Scott Kirby states he does not anticipate a vaccination prerequisite for travel in just the United States, but he stated it is achievable for some worldwide journey.

When questioned no matter if passengers will need to have to get vaccinated as a condition to fly, Kirby told CNN’s Victor Blackwell on Wednesday that “it is a federal government issue, but I suspect that it will not materialize domestically.”

On Wednesday, President Joe Biden achieved with Kirby and other executives from organizations that are mandating that employees get vaccinated.

Kirby suggests by increased employer mandates, he thinks that the United States could see an 80% to 90% vaccination rate.

Biden “questioned us to do all the things we could with fellow CEOs or any one we have been in get hold of with to persuade other individuals to do the very same factor,” Kirby stated.

3 other US airlines take a different route

The CEOs of Southwest Airlines, American Airways and Delta Air Lines say they are not requiring unvaccinated employees to get the shot.

In an internal memo acquired by CNN, Southwest Airways CEO Gary Kelly explained the airline will “proceed to strongly persuade” that personnel get vaccinated, but the airline’s stance has not shifted.

American Airways CEO Doug Parker stated in a New York Periods podcast interview that the airline is supplying employees who get vaccinated by the close of this month one further day of family vacation in 2022.

But the firm is not putting a mandate in area, he claimed.

In Could, Delta turned the first important provider to call for that all new hires be vaccinated, but the organization has not issued a mandate for all workforce.
