Denver International Airport will be conducting reviews of Frontier, Southwest and United airlines following delays and cancellations this past week.
The reviews come after airlines stranded travelers across the country following last week's storm. But the problem has persisted beyond the weather for Southwest, due to an outdated scheduling system and the structure of its flight patterns that exacerbated the problem.
As of Wednesday afternoon, Southwest had canceled or delayed more than 300 of its flights out of Denver for the day. More than 270 of its flights for Thursday were proactively canceled.
"I believe it's critically important that we seize the opportunity to learn from every incident," wrote DIA CEO Phillip Washington in a press release Wednesday.
"Though airline accountability is imperative for this latest event, we want to determine why flight disruptions and delays happened and how we can improve the overall operations here at DEN going forward for the good of our flying passengers."
Washington also wrote that the airport is increasing security around the baggage claim as lost luggage piles up, and that DIA is giving out blankets, diapers and other essentials to people stuck at the airport.
DIA isn't the only one looking into Southwest after the recent meltdown; the federal government recently announced an investigation into the airline's operations.
