Reuters has reported that some airlines are reviving some of their routes as they test increased capacity amid COVID-19 pandemic, the news source said.
Travelers will have to check restrictions at their destination. Hawaii recently extended its mandatory 14-day quarantine for arriving travelers through the end of June, the U.K. is planning to impose a similar restriction on non-E.U. arriving travelers, and the US has its own rules for returning international travelers, including a self-quarantine requirement for some.
San Francisco International Airport said this week that it expects to see some international service revived in June.
