Several airlines have cancelled flights to and from Denver International Airport (DIA) due to a blizzard known as Winter Storm Wesley.
The Denver Post reported that the storm had led to 183 flight cancellations and 44 flight delays on Thursday, as well as more than 750 cancellations on Wednesday.
United Airlines cancelled 74 (17%) of its flights and delayed a further nine, while SkyWest cancelled 49 flights on Thursday, reported FlightAware.
DIA urged passengers to check their flight status before reaching the airport, while airport staff worked through the night to clear the runways.
Southwest Airlines and United Airlines cancelled around 200 flights each in anticipation of the blizzard on Wednesday.
SkyWest and Frontier Airlines also cancelled 158 and 40 flights respectively. Other affected airlines include Alaska Airlines, British Airways, and Delta.
To minimise inconvenience, several airlines have offered travel waivers to affected passengers so that they can alter their flights without paying a penalty.
Passengers will also be entitled to a refund, even if they purchased a non-refundable ticket.
In March, DIA was forced to shut down all six of its runways and cancel approximately 1,400 flights as a blizzard hit the airport.
Wind gusts of 80mph to 96mph were reported at the airport, producing white-out conditions on the runways.
