  • A frigid polar vortex is wreaking havoc on air travel at some of the nation's busiest airports, including Chicago and Atlanta.
  • More than 1,000 flights were canceled by 9 a.m. Tuesday, adding to the hundreds more disrupted on Monday.
  • Many airlines have waived change fees for customers flying through affected airports.

More than 900 flights were canceled Tuesday morning, adding to the more than 1,000 disrupted on Monday, as winter weather from Chicago to Boston and Atlanta wreaks havoc on air travel.

At United's Chicago hub, where the National Weather Service predicts a high temperature of 5 degrees on Tuesday with frigid windchill extending well into the negatives, more than 150 flights were canceled by 9 a.m., according to FlightAware.Advertisement

"We expect to operate on a reduced schedule throughout the week," United spokesperson Robert Einhorn told Business Insider. He also noted that the airline is coping with the storm by adding additional ramp workers at O'Hare so that employees may work shorter shifts in the cold, as well as moving some equipment inside away from the elements.

Across town at Midway, Southwest's largest hub, things were just as bleak, with more than 250 flights canceled as of 9 a.m. Tuesday. Those travel headaches will only compound the delays from Monday, when 1200 flights were cancelled, according to the USA Today.

Southwest Airlines said through a spokesperson that "customers will see flight reduction due to weather," mostly in Chicago and Milwaukee.
