475 flights were canceled at DIA yesterday.
Oh, and a lot of the stranded passengers were Air Force Academy cadets trying to get home.
I make it a point to avoid DIA. Their weather is always weird. Got stuck there overnight in June 2018 because of a sleet storm of all things. The weather was so bad no flights came in or went out and then the pilots they had all ran out of flight time so that when our plane was finally okayed to leave 16 hrs later they couldn’t find a pilot for it. I said never again and avoid the airport.
