Honestly, if you’re trying to figure out how much is a flight to Chicago, the answer is usually "it depends," which I know is a frustratingly vague thing to hear. But here is the reality of the Windy City’s aviation market: it is one of the most competitive hubs on the planet. You have O'Hare (ORD), which is a massive global fortress for United and American, and then you have Midway (MDW), which is essentially the kingdom of Southwest Airlines.
Prices swing wildly.
One week you might find a $54 round-trip ticket from Denver, and the next week, because there’s a massive medical convention at McCormick Place, that same seat is $450. I’ve seen people lose hundreds of dollars just because they didn't realize Lollapalooza was happening the weekend they decided to visit. Chicago isn't just a city; it's a massive logistics engine, and the "engine" gets expensive when it’s busy.
The Raw Numbers: What’s a "Good" Deal?
Let’s talk brass tacks. If you are flying from a major domestic hub like New York, Dallas, or Atlanta, a "good" price for a round-trip ticket to Chicago generally sits between $130 and $220. If you see anything under $100, you should probably book it immediately without overthinking the legroom.
From the West Coast—think LAX or SFO—you’re looking at a different ballgame. Expect to pay $250 to $400 for a standard economy seat. International travelers coming from London or Tokyo are obviously in a different bracket, often seeing prices range from $600 to $1,200 depending on the season.
It's weirdly unpredictable sometimes.
I recently tracked a flight from Miami to O'Hare that dropped to $88 on a Tuesday morning and spiked to $310 by Wednesday afternoon. Why? Probably because a carrier like Spirit or Frontier adjusted their capacity, and the "legacy" carriers followed suit. Chicago is one of the few places where the presence of low-cost carriers (LCCs) actually forces the big guys like American Airlines to lower their fares on specific routes just to stay in the game.
Why the Airport Choice Changes Everything
You have two main choices: O’Hare International (ORD) and Midway International (MDW). They are not the same, and picking the wrong one can cost you more than just money—it can cost you hours in traffic.

O’Hare is the behemoth. It’s where the international flights land. It’s also where you’ll find the most "basic economy" traps. United and American dominate here. If you’re looking at how much is a flight to Chicago on a site like Google Flights or Expedia, O'Hare usually shows the lowest "headline" price. But wait. Is that price for a "Basic Economy" ticket that doesn't allow a carry-on bag? Frequently, yes. By the time you add a suitcase, that $120 flight is suddenly $180.
Midway is different.
It’s smaller, easier to navigate, and dominated by Southwest Airlines. Because Southwest doesn't show up on most third-party search engines, people often miss out on their deals. They allow two free checked bags. If you’re a heavy packer, a $200 flight to Midway might actually be cheaper than a $140 flight to O'Hare plus baggage fees.
Seasonality is a Beast in the Midwest
Winter in Chicago is brutal, and the flight prices reflect that. Except for the holidays, January and February are the cheapest times to fly. You can get to Chicago for peanuts if you don't mind the "Lake Effect" snow and the wind that feels like it’s peeling the skin off your face.
But summer?
Summer in Chicago is glorious. The 18 miles of lakefront trails are packed, the rooftop bars are buzzing, and the flight prices soar. June through August is peak season. If you aren't booking at least 6 weeks in advance for a summer trip, you’re going to get hammered on the price.
The "Secret" Price Drivers
Most people forget about conventions. Chicago has one of the largest convention centers in North America. When 60,000 radiologists or tech developers descend on the city for a week, every hotel room and every flight seat gets sucked up.

If there is a massive trade show during your dates, the "average" price for a flight will skyrocket. It doesn’t matter if it’s a random Tuesday in October; if the "National Restaurant Association" is in town, you’re paying a premium.
Also, consider the day of the week. Chicago is a massive business hub. Mondays and Thursdays/Fridays are the most expensive days because that's when the consultants and corporate execs are flying in and out. If you can fly on a Tuesday or a Wednesday, you’ll often save 30% or more. It sounds like a cliché, but in a business-heavy market like Chicago, it’s a law of nature.
Breaking Down the Carriers
Not all airlines are created equal when heading to the 312 area code.
- United & American: They own O'Hare. They offer the most frequency, which is great if your flight gets cancelled, but you pay for that convenience.
- Southwest: The Midway king. Great for families and those who refuse to travel light.
- Spirit & Frontier: They often have the lowest "sticker price." Just be prepared to pay for your water, your bag, and maybe even the air you breathe. If you can fit everything in a backpack, these are your best friends.
- Delta: They don't have a hub here, but they run a very tight "shuttle" style service from places like Minneapolis, Detroit, and Atlanta. Sometimes they offer aggressive pricing to lure people away from the United/American duopoly.
Real-World Examples of Recent Fares
I looked at some data from the Bureau of Transportation Statistics (BTS) and recent booking trends for 2026. On average, the "domestic itinerary fare" for Chicago hovers around $360, but that includes a lot of expensive last-minute business travel.
For the average vacationer:
- NYC to ORD: $115–$190 (Look for JetBlue or United)
- LAX to ORD: $210–$350 (Look for American or Alaska)
- ATL to MDW: $140–$220 (Southwest is usually the play here)
- DFW to ORD: $150–$250 (Spirit vs. American competition is fierce here)
How to Actually Secure the Lowest Fare
Stop clearing your "cookies." That’s a myth that won't die. Airlines don't track your specific browser to raise prices; they use sophisticated "Revenue Management" software that tracks overall demand.

Instead, use Google Flights to look at the "Date Grid." It’s a literal goldmine. You can see how shifting your trip by just 24 hours can save you $100. Also, set a price alert. Since Chicago has so much "capacity" (meaning lots of planes), airlines frequently have "flash sales" to fill seats that aren't selling. If you get a notification that a flight dropped to $140, buy it. Don't wait for $120. That $20 difference isn't worth the risk of the price jumping to $300 while you sleep.
The Hidden Costs of O'Hare
When asking how much is a flight to Chicago, you have to factor in the ground.
Getting from O'Hare to the Loop (the city center) can be pricey. An Uber or Lyft during rush hour can easily hit $60 or $70. If you take the "L" (the Blue Line train), it’s only $5. Midway is closer to the city and the Orange Line train is also cheap, but an Uber from there might still run you $40. If you find a flight that is $20 cheaper to O'Hare but your hotel is on the South Side, you might end up spending more on the backend in transit costs.
Final Practical Steps for Your Booking
To get the absolute best price for your Chicago trip, follow this sequence:
- Check the Convention Calendar: Go to the Choose Chicago website and look for major events at McCormick Place during your dates. If it's clear, proceed.
- The 21-Day Rule: Never book a flight to a major hub like Chicago less than 21 days out. That's when "business pricing" kicks in and economy seats start costing as much as first-class seats used to.
- Compare ORD vs. MDW: Open two tabs. One for Google Flights (O'Hare) and one for Southwest.com (Midway).
- Factor in the Bag: If you need a suitcase, add $60 to any "Basic Economy" price you see on United or American before you compare it to a Southwest fare.
- Book the Mid-Week Slot: Aim for a Tuesday-to-Tuesday or Wednesday-to-Wednesday itinerary if your schedule allows.
Chicago is a city that rewards the prepared. Whether you’re coming for the deep-dish pizza, the architecture tours, or a meeting at the Willis Tower, the money you save by timing the market can be spent much better on a fancy dinner in the West Loop. Pay attention to the airport choice, avoid the massive trade shows, and don't be afraid of the "L" train. That’s how you handle the Windy City like a local.
The most important thing to remember is that Chicago is a high-volume market. This means prices are constantly in flux. If you see a fare that fits your budget today, the odds of it being there tomorrow are slim. Grab it when the numbers make sense and don't look back. Chicago is worth the trip, even if you have to pay a little extra for a seat that actually has a window.
