Understanding Your Airport Options
When you search for plane tickets from Chicago to Houston, pay close attention to the airports. Both cities feature two major airports, giving you plenty of combinations to choose from based on your location and preferred airline.
Chicago Departure Airports
Chicago offers two massive transit hubs. Depending on where you live or stay in the city, one might be much more convenient than the other.
Chicago O’Hare International Airport (ORD)
Chicago O’Hare Intl (ORD) is one of the busiest airports in the world. It sits about 16 miles northwest of downtown Chicago. If you fly with legacy carriers like United Airlines or American Airlines, you will likely depart from here. O’Hare offers extensive dining options, numerous lounges, and easy access via the CTA Blue Line.
Chicago Midway International Airport (MDW)
Located just 9 miles southwest of downtown, Chicago Midway (MDW) is smaller and often easier to navigate than O’Hare. It serves as a massive hub for Southwest Airlines. If you value quick security lines and close proximity to the city center via the CTA Orange Line, Midway is a fantastic choice for your departure.
Houston Arrival Airports
Just like Chicago, Houston gives you two distinct arrival options. Selecting the right one can save you hours of driving time once you land in Texas.
George Bush Intercontinental Airport (IAH)
Houston George Bush Intercontinental (IAH) is the primary international hub for the city, located about 15 miles north of downtown Houston. It serves as a major fortress hub for United Airlines. If you book plane tickets from Chicago to Houston on a major legacy carrier, you will almost certainly land here.
William P. Hobby Airport (HOU)
William P. Hobby (HOU) is located just 7 miles south of downtown Houston. This airport is significantly smaller and easier to navigate. Southwest Airlines dominates the traffic here. If your final destination is southern Houston or Galveston, landing at Hobby will save you considerable time.
Top Airlines Offering Plane Tickets from Chicago to Houston
You have plenty of options when choosing who to fly with. The route features heavy competition between budget carriers and full-service legacy airlines.
Budget Airlines for Cheap Flights
If your primary goal is to find the absolute lowest price, you should look into ultra-low-cost carriers.
- Spirit Airlines: Spirit frequently offers incredibly cheap base fares out of O’Hare. However, you must account for extra baggage fees if you plan to bring more than a small personal item.
- Frontier Airlines: Similar to Spirit, Frontier offers deeply discounted plane tickets from Chicago to Houston. They run nonstop flights that get you to Texas quickly, provided you read the fine print regarding seat selection and carry-on bags.
Major Carriers for Comfort and Perks
If you prefer a more inclusive experience with free carry-on bags and complimentary snacks, consider the major legacy carriers.
- United Airlines: United offers the highest frequency of direct flights between ORD and IAH. They offer multiple cabin classes, including Basic Economy, standard Economy, and First Class.
- Southwest Airlines: Famous for their “Bags Fly Free” policy, Southwest dominates the MDW to HOU route. If you need to check luggage, Southwest often provides the best overall value.
- American Airlines & Delta: While United and Southwest dominate the direct routes, you can also find competitive round-trip tickets on American and Delta, though some of these options might include a short layover.
Best Times to Buy Plane Tickets from Chicago to Houston
Timing is everything when trying to score travel deals. By understanding seasonal trends and airline pricing algorithms, you can save a significant amount of money.
Cheapest Months to Fly

During these shoulder seasons, the weather is relatively pleasant, but major holiday travel has not yet peaked. January is also a great month for budget travelers, as demand drops significantly right after the winter holidays.
Best Days of the Week to Book and Fly
To secure the best rates, try to schedule your departure for a Tuesday or Wednesday. Mid-week flights consistently show lower prices compared to weekend departures. Additionally, booking in advance—usually around 40 to 60 days before your trip—yields the best results. Last-minute flights generally spike in price as business travelers buy up the remaining seats.

Tips for Getting the Best Deals on Plane Tickets from Chicago to Houston
Finding cheap plane tickets from Chicago to Houston requires a little bit of strategy. Follow these best practices to ensure you never overpay for your seat:
- Set Price Alerts: Use digital travel tools to track your preferred travel dates. You will receive an email the moment the airline drops the price.
- Be Flexible: If you can shift your travel dates by a day or two, you can often find a massive drop in fare prices.
- Mix and Match Airlines: You do not have to book a single round-trip ticket. Sometimes, buying a one-way ticket on United to get there, and a one-way ticket on Southwest to get back, creates the cheapest overall itinerary.
- Check Nearby Airports: Always search flights for both ORD and MDW, as well as both IAH and HOU. An airport just a few miles further away might save you hundreds of dollars.
- Factor in Hidden Fees: A $50 ticket on a budget airline might seem like a steal, but if they charge you $60 for a carry-on bag, a $90 ticket on a legacy carrier actually provides a better deal.
