 The Biden administration has lifted its requirement that international travelers test negative for COVID-19 within a day before boarding a flight to the United States, ending one of the last remaining government mandates designed to contain the spread of the coronavirus. The requirement for a negative COVID-19 test before flying to the US dates to January 2021.

The Centers for Disease Control and Prevention announced the changes last week. The health agency said it will continue to monitor the state of the pandemic and will reassess the need for a testing requirement if the situation changes.

“This step is possible because of the progress we’ve made in our fight against COVID-19,” said US Health Secretary Xavier Becerra.

Airline and tourism groups have been pressing the administration for months to eliminate the testing requirement, saying it discourages people from booking international trips because they could be stranded overseas if they contract the virus on their trip.

Roger Dow, president of the US Travel Association, called lifting the testing rule “another huge step forward for the recovery of inbound air travel and the return of international travel to the United States.”

Airlines argued that the rule was put into effect when few Americans were vaccinated — now 71% of those 5 and older are fully vaccinated, according to CDC figures. They also complained that people entering the US at land borders are not required to test negative for COVID-19, although they must show proof of vaccination.

US airlines estimate that dropping the test requirement will mean 4.3 million more passengers in one year.

It is unclear, however, whether airlines can boost flights quickly enough to handle that kind of increase. Airlines facing a shortage of pilots have already scaled back their original schedules for the peak summer vacation season.
