Why Denver to Chicago Flights are So Popular
People love taking denver to chicago flights for many reasons. For one, both cities are major homes for big airlines. Denver is a huge “hub” for United and Frontier, while Chicago is a primary base for United and American. This means there are dozens of planes flying back and forth every single day.
I remember the first time I took this flight. I was amazed at how quickly the landscape changed. You start with the Rocky Mountains in your rearview mirror and, in less than three hours, you see the massive Chicago skyline appearing over the flat plains. It is a vital link for families, sports fans, and business travelers alike.
Checking Denver to Chicago Flights Today
If you need to find denver to chicago flights today, you are in luck. Because this route is so common, airlines usually run flights almost every hour. If you have a sudden meeting or a family emergency, you can almost always find a seat. However, “last-minute” usually means “more expensive,” so keep that in mind!
To see the latest status for denver to chicago flights today, I always recommend using a flight tracker app. Airports like Denver (DEN) can sometimes have mountain winds that cause short delays. Checking your flight status before you leave for the airport can save you a lot of sitting around at the gate. Most direct flights today will get you to Chicago in about 2.5 hours.
Choosing the Right Chicago Airport
When booking denver to chicago flights, you actually have two choices for where to land. Most people fly into O’Hare International Airport (ORD). It is huge and has tons of shops. However, Southwest Airlines mostly flies into Midway International Airport (MDW). Midway is smaller and often much easier to navigate.
If your final destination is downtown Chicago, O’Hare has the “Blue Line” train, and Midway has the “Orange Line.” Both are cheap and take you right into the heart of the city. Personally, I prefer Midway because I can get from the plane to a taxi in about 15 minutes. O’Hare is great if you are connecting to an international flight!
Best Airlines for the Journey
There are four main “kings” of the denver to chicago flights route. United Airlines offers the most daily flights, often with 10 or more departures. American Airlines is also a big player. Both of these are great if you like earning frequent flyer miles or want a bit more legroom in first class.
If you want to save money, look at Frontier or Southwest. Frontier is a “low-cost” carrier. This means the ticket is cheap, but you might pay extra for a carry-on bag. Southwest is a fan favorite because they let you check two bags for free! When I travel with a lot of luggage, Southwest is always my go-to choice for this trip.
How to Find the Lowest Fares
Everyone wants a deal on denver to chicago flights. The secret is timing. Based on recent data, booking about 40 to 70 days in advance usually gets you the best price. If you wait until the week of the flight, prices can double. Mid-week flights on Tuesdays and Wednesdays are usually cheaper than flying on a Friday or Sunday.
Another trick I use is searching for flights in “incognito mode” on my browser. Some people believe travel sites raise prices if they see you searching the same route over and over. While that is debated, it never hurts to try! Also, flying early in the morning (the “red-eye” or “dawn patrol”) can save you fifty dollars or more.
What to Expect During the Flight
The flight time for denver to chicago flights is usually around 2 hours and 40 minutes. Since you are flying east, you will actually lose an hour because of the time zone change. If you leave Denver at 8:00 AM, you will land in Chicago around 11:40 AM. It feels like a long morning, but the flight itself is quite short.
Most planes on this route are “narrow-body” jets like the Boeing 737 or Airbus A320. These are standard planes with three seats on each side of the aisle. On United or American, you might get a small snack like pretzels. On Southwest, you’ll definitely get their famous crackers. I always bring a book or download a movie because the views of the Midwest plains can get a bit repetitive!
Navigating Denver International Airport (DEN)
Denver’s airport is famous for its white tent-like roof that looks like snowy mountains. When taking denver to chicago flights, give yourself plenty of time. DEN is very large. You have to take a train from the main terminal to your gate (A, B, or C gates). It’s a fun ride, but it adds about 10 minutes to your journey.
I always tell my friends to look for the “Blue Mustang” statue (nicknamed Blucifer) on the way in. It’s a giant blue horse with glowing red eyes! Once inside, the security lines can be long, especially on Monday mornings. If you have TSA PreCheck, you will breeze through much faster. There are great places to grab a breakfast burrito before you board.
Arriving in the Windy City
Once your denver to chicago flights touch down, the real fun begins. If you land at O’Hare, follow the signs for “Baggage Claim” or “Ground Transportation.” The airport is very spread out, so expect some walking. If you are hungry, O’Hare has some of the best airport food in the country, including Tortas Frontera by Rick Bayless.
Chicago weather can be a surprise. Even if it is sunny in Denver, Chicago might be windy or rainy. I always pack a light jacket in my carry-on just in case. Once you leave the airport, the skyline is about 45 minutes away by car or train. The energy of the city is infectious, and you’ll be glad you made the trip!
Best Times of Year to Visit
While you can find denver to chicago flights year-round, some months are better than others. Summer (June to August) is beautiful because of the lake breeze and festivals. However, it is also the most expensive time to fly. Fall is my personal favorite because the weather is crisp and the city looks gold.
Winter in Chicago can be very cold and snowy. If you don’t mind the chill, you can find incredibly cheap denver to chicago flights in January and February. Just be prepared for potential snow delays. If you want the perfect mix of low prices and good weather, try visiting in May or September.
