(CNN) — Hundreds of flights were canceled Wednesday at Denver International Airport (DIA) as a winter storm sweeps across the Rocky Mountain region, according to data from FlightAware.
According to the flight tracking site, almost 320 flights bound for or departing from DIA had been canceled as of 7:45 p.m. ET, with almost 700 flights delayed.
Almost 200 of the cancellations were Southwest Airlines flights, FlightAware indicates.
On Tuesday, more than 180 flights to or from the Denver airport were canceled.
In a statement to CNN, a DIA spokesperson said despite the cancellations, airport operations are running smoothly.
“Many airlines decide to preemptively cancel flights within a 24 hour period to maintain regular operations,” the spokesperson said.
Still, the airport advises passengers to check with specific airlines for the most up-to-date information on their flights.
