The US transportation department has lifted its emergency order to cut flights across the country, saying enough air traffic controllers are now coming to work to alleviate safety concerns.
During the government shutdown that started in October, there was a rise in absences of air traffic controllers, who - as essential employees - were required to work without pay, which led airports to delay or ground flights.
The Federal Aviation Administration (FAA) then ordered airlines from 7 November to cut scheduled takeoffs in order to prevent safety issues.
Since the shutdown ended last week, staffing levels "have continued to snap back", the department said, just in time for busy Thanksgiving travel.
More than 6 million people in the US are expected to fly during the Thanksgiving holiday - about 2% more than last year - according to the major travel group AAA, which notes that the period is the single busiest holiday for travel in the US.
