The website FlightAware.com said 12,235 flights were canceled between Friday and Monday because of the storm, which was dubbed Winter Storm Jonas. The blizzard dumped as much as two feet of snow on the nation's capital and surrounding areas.
Another 12,219 flights were delayed between Saturday and Monday, according to the website.
"We're digging out of 29.3" of snow at IAD, and we plan to gradually restart operations there & at surrounding airports on Monday afternoon," United Airlines tweeted.
