Winter weather: Airports in Illinois, Indiana, Missouri, Texas added to waiver lists

After a few days of spring-like weather, winter has once again tightened its grip on parts of the Rocky Mountains and areas of Texas and Oklahoma, prompting flight cancellations at airports in Denver and Salt Lake City.

In fact, Denver International Airport, which saw about three inches of snow, had 176 cancellations and more than 600 delays on Monday, according to flight-tracking website FlightAware. Operations have since gotten back under control with just 17 cancellations and 42 delays as of 11 a.m. EST Tuesday morning.

The storm, dubbed Winter Storm Kade, is expected to move across the Plains states and the interior Northeast over the next few days.

On Tuesday afternoon, new waivers were issued for airports in Illinois and Missouri as well as additional airports in Texas and Oklahoma. Those are on top of the waivers previously issued for Colorado, Utah, Texas and Oklahoma.

The waivers allow impacted passengers to reschedule their travel without incurring a penalty. More airports are likely to be added as the storm moves eastward, so check back frequently for updates.
