I missed my connecting flight because our plane took off ten minutes late and then when we got to the airport another plane was in our shoot waiting to get fueled up and that took 30 minutes so I missed my connecting flight. I asked if I could get off and they assured me the plane would most likely wait for me since they know what time the planes get in because of an app. I was not happy. I had to wait till 7:25 to board the next flight and then that was delayed. Gates changed till 9:20. Terrible

FAQs about flying to Denver

Denver climate

Despite Denver’s reputation as a ski paradise, the city does not have very harsh winters. Denver nestles in the foothills of the Rockies, on the high plains. The Chinook winds warm up the city to average temperatures that are well above other cities on the same latitude.

Getting around Denver

You can walk around downtown Denver easily or take public transportation. The 16th Street Mall has a free bus service running down the length of it. It stops every two blocks. To get around Denver, its suburbs and outlying communities, like Boulder and Evergreen, you can take the Regional Transportation District (RTD). It offers bus and light-rail services and has free transfer tickets, but you’ll need exact change. A great way to sightsee is hopping on the open-air Platte Valley Trolley, which has half-hour tours on its “Denver Sightseeing Route” in the warmer months. If you’re heading out of town for the day, you’ll need to rent a car. Be mindful of driving conditions during winter; storms can make driving treacherous.
