Domestic flights at 40 of the country's busiest airports will be affected as officials try to ease pressure on air traffic controllers
Airports have been grappling with air traffic controller shortages, who are either calling in sick or taking side jobs as they work without pay during the federal government shutdown
The Federal Aviation Administration (FAA) says reductions will start at 4% of internal flights before rising to the full 10% by the end of next week - it warns up to 4,000 flights per day could be affected
Several of the largest US airlines are assuring customers they'll be able to get full refunds for the cancelled flights. A ground stop has been ordered at San Francisco International Airport because of staffing shortages.
It means a stoppage in flights that are due to arrive in the city, and it could also impact departures.
We've seen similar ground stoppages happen at a handful of US airports during the government shutdown.
For flyers in San Francisco, the ground stop will mean delays and perhaps cancellations of flights.
Nick Daniels, the president of the National Air Traffic Controllers Association, says they are being used as political pawns in the government shutdown.
"We know the problems are going to get worse. They're going to increase, and anything that helps improve safety, we 100 percent stand by ensuring the safety of the American flying public," he told CNN.
Daniels said air traffic controllers are going to continue to show up and "do the job".
"We are going to do everything we can, but what we can't do is somehow, suddenly put money in our own pocket," he said. "We need Congress to open the government to do that."
This shutdown, which began on 1 October, has caused unprecedented disruptions in the country.
Food aid programmes have been paused, hundreds of federal workers remain unpaid, and there are huge flight disruptions at major airports like here in DC.
For weeks, Democrats have refused to vote to reopen the government without major investments in reducing health care costs.
The revised bill put forward will likely keep the federal government's lights on past Thanksgiving.
But if significant changes to health care aren’t in the bill, it’s unlikely to pass.
