The program will first only be offered for those traveling on United from San Francisco International Airport (SFO) to Hawaii, which will begin starting Oct. 15, the airline said in a statement.
It will offer rapid testing at the airport or a self-collected, mail-in test ahead of the trip.
Dignity Health will be providing the tests at the airport. The results arrive in approximately 15 minutes, which is how they are able to offer them at the airport, the company said. The mail-in test option will be done by the company, Color, and tests should be done at least 10 days prior to the trip and within 72 hours of returning home.
The airline also announced it hopes to start expanding this program beyond these two locations later this year.
"Our new COVID testing program is another way we are helping customers meet their destinations' entry requirements, safely and conveniently," said Toby Enqvist, chief customer officer at United. "We'll look to quickly expand customer testing to other destinations and U.S. airports later this year to complement our state-of-the-art cleaning and safety measures that include a mandatory mask policy, antimicrobial and electrostatic spraying and our hospital-grade HEPA air filtration systems."
