A winter storm is freezing travel in some major cities in the Northeast.

The blizzard-like conditions forced airlines to cancel nearly 5,000 flights on Tuesday and more than a 1,000 more on Wednesday. That includes flights in and out of Houston's George Bush Intercontinental Airport to Washington, D.C., New York, Chicago and more.

“I really thought that they would cancel flights,” traveler Dana McCarthy said. “Looking all the way from home to the airport with the weather it looks very, very bad up there. I know other flights have flown into and out of Boston, so I think they’re pretty prepared.”

Airport officials recommend flyers check their flight status before heading to the airport.
