LAS VEGAS (KLAS) — Thousands of airline passengers are in for another day of chaos at airports across the country and in Las Vegas as more flights are either delayed or canceled due to winter storms and operational challenges.

Harry Reid International Airport is showing as the third worst airport Tuesday when it comes to cancellations. There were 230 canceled flights. The airports in Denver and Chicago Midway top the list, according to FlightAware, a flight tracking website.

By Tuesday at noon, Southwest Airlines had already canceled nearly 2,600 flights of the more than 3,000 total flights canceled in the United States. Southwest will only be flying one-third of its scheduled flights for today. It canceled more flights Monday and Tuesday than any other airline in the country.

All Southwest Airlines departures from Southern California airports, such as LAX, San Diego, Burbank, John Wayne, and Ontario International show “unavailable” for booking flights until after New Year’s Eve.

It doesn’t look like it will be much better on Wednesday, according to FlightAware, Southwest already is reporting nearly 2,500 flights will be canceled.

The U.S. Department of Transportation is looking into how Southwest Airlines has handled the cancellations and delays and whether the Dallas-based carrier is complying with its customer service plan.

You can read the airline’s service plan here. There is also the U.S.D.O.T Passenger Bill of Rights for passengers aggrieved by airline actions. Southwest does have a webpage for travel disruption that gives information where you can check your flight, rebook a flight, or request a refund for expenses you may be entitled to.
