Route Overview: Phoenix to Chicago
Traveling from the Valley of the Sun to the Windy City is one of the most popular domestic corridors in the United States. Whether you are flying for business in the Loop or seeking the world-class museums of the lakefront, cheap flights from Phoenix to Chicago provide a vital link between the Southwest and the Midwest. This route connects Phoenix Sky Harbor International Airport (PHX) with Chicago O'Hare International Airport (ORD), a global aviation hub. Passengers can expect a seamless transition from the desert heat to the bustling metropolitan energy of Illinois.

Flight duration and schedule
The PHX to ORD nonstop flight typically covers the distance in approximately 3 hours and 25 minutes to 3 hours and 45 minutes. Westbound flights from Chicago to Phoenix usually take slightly longer, closer to 4 hours, due to prevailing headwinds. Airlines maintain a robust schedule with departures starting as early as 6:00 AM and continuing through late-night red-eye options. For travelers on this page, it is important to note that Chicago is in the Central Time Zone, which is one or two hours ahead of Phoenix depending on the time of year, as Arizona does not observe Daylight Saving Time.
Nonstop vs one-stop options
Most travelers prefer the convenience of a direct flight. However, if you are looking for the absolute lowest price, one-stop itineraries through hubs like Denver (DEN), Dallas (DFW), or Las Vegas (LAS) can sometimes offer savings. Common connecting points for this route include United Airlines hubs or American Airlines facilities. While a nonstop flight is the most efficient, a connection might add 2 to 4 hours to your total travel time but could reduce the fare during peak holiday periods.
Distance and typical aircraft
The great circle distance between PHX and ORD is approximately 1,440 miles. This distance is perfectly suited for narrow-body aircraft. You will most commonly find yourself on a Boeing 737 (various series) or an Airbus A320 family aircraft. These planes are equipped with modern amenities, and many now offer high-speed Wi-Fi and in-flight entertainment streaming to your personal devices.
Airlines, Alliances and Aircraft on the PHX-ORD Route
Several major carriers dominate this route, ensuring competitive pricing and frequent service. American Airlines and United Airlines are the primary legacy carriers, both maintaining significant hubs at O'Hare. Southwest Airlines also services the Phoenix to Chicago market, though they primarily fly into Chicago Midway (MDW). For those specifically targeting ORD, Frontier Airlines often provides the most budget-friendly alternatives.
American Airlines and the Oneworld Alliance
American Airlines offers multiple daily nonstops. As a Oneworld member, they provide excellent connectivity for passengers continuing to international destinations from Chicago. Their fleet on this route often features the Boeing 737-800, which includes a dedicated First Class cabin and Main Cabin Extra seating for additional legroom.
United Airlines and Star Alliance
United Airlines treats the PHX-ORD route as a high-frequency shuttle between two of its major focus cities. Being part of the Star Alliance, United allows travelers to earn and redeem miles across a vast global network. They frequently utilize the Airbus A319 and A320 on this leg, offering United First, Economy Plus, and standard Economy seating.
Frontier Airlines: The Low-Cost Leader
For budget-conscious flyers, Frontier Airlines (F9) is a standout. We recently found a live one-way Economy fare for 2026-10-25 at $269 on F9. This nonstop flight takes about 3h 27m. It is important to remember that prices change daily and low-cost carriers like Frontier unbundle their services, meaning you pay only for what you need.
Cabin classes and seat tips
On legacy carriers, First Class offers a 2-2 configuration with complimentary meals and alcoholic beverages. In Economy, try to secure a seat in the exit row for maximum legroom. On Frontier Airlines, all seats are standard, but you can upgrade to 'Stretch' seating at the front of the cabin for a more comfortable 3-hour journey.
Departure Airport Guide: PHX
Phoenix Sky Harbor International Airport is frequently ranked as one of the most traveler-friendly airports in the United States. Located just 3 miles east of downtown Phoenix, it is easily accessible and well-organized.
Terminals and check-in
PHX has two active terminals: Terminal 3 and Terminal 4. American Airlines operates exclusively out of Terminal 4, which is the largest and busiest. United Airlines and Frontier Airlines are located in Terminal 3. Both terminals offer a wide array of Southwest-inspired dining options and local boutiques. Security wait times are generally manageable, but it is recommended to arrive 2 hours before your PHX to ORD departure.
Getting to the airport
The PHX Sky Train is a free automated people mover that connects the airport with the Valley Metro Rail at 44th Street and Washington. This is the most cost-effective way to reach the airport from Tempe, Mesa, or Downtown Phoenix.
Parking and rideshare pickup
Rideshare services like Uber and Lyft have designated pickup zones at both terminals. For those driving, the East Economy lot offers the best balance of price and proximity, with the Sky Train providing quick access to the terminal doors.
Arrival Airport Guide: ORD
Chicago O'Hare International Airport is a massive complex located about 17 miles northwest of the Loop. It is one of the busiest airports in the world, so having a plan upon landing is essential.
Terminals and baggage claim
American Airlines typically arrives at Terminal 3, while United Airlines utilizes Terminal 1. Frontier Airlines usually arrives at Terminal 5, the international terminal, which recently underwent a major expansion. Baggage claim areas are located on the lower level of each terminal. Follow the overhead signs carefully, as the distances between gates and the exit can be significant.
Ground transportation into the city
The CTA Blue Line train is the most reliable way to reach downtown Chicago, especially during rush hour. The station is located on the lower level of the main terminal complex. For a more direct route, taxis and rideshares are available, though the journey to the Loop can take anywhere from 40 to 90 minutes depending on the infamous Chicago traffic.

Finding cheap flights from Phoenix to Chicago requires an understanding of seasonal demand. Chicago is a seasonal city, with peak travel occurring during the warm summer months and around major holidays.
Best days and months to book

Baggage Information and Fees
Baggage policies vary significantly between carriers. Always check your specific fare class, as 'Basic Economy' often excludes a full-sized carry-on bag.
| Airline | Carry-on | First checked bag | Second checked bag |
|---|---|---|---|
| American | Included | $35 - $40 | $45+ |
| United | Varies by fare | $35 - $40 | $45+ |
| Frontier | Fee applies | Fee applies | Fee applies |
| Southwest | 2 Bags Free | Included | Included |
How to avoid baggage fees
The best way to avoid fees is to fly Southwest Airlines (into MDW) or to hold a co-branded airline credit card which often waives the first checked bag fee for the cardholder and companions. Alternatively, packing in a high-quality personal item that fits under the seat can save you significantly on Frontier Airlines.
Weather in Chicago Through the Seasons
Chicago weather is famously unpredictable. The 'Windy City' nickname refers more to its politics than its breeze, but Lake Michigan does create unique microclimates.

| Summer | 70°F - 90°F | Breathable cotton and sunblock. |
