7 Ways to Get Cheap Airline Tickets to and from Chicago

Chicago has two major airports, a United hub at O'Hare, and a Southwest stronghold at Midway. That should make cheap airline tickets Chicago easy to find. Yet fares swing by hundreds of dollars depending on the day you fly, the airport you pick, and the week you book. Pay attention to those three things and you stop overpaying.

Here is the short answer. Compare fares across many airlines at once, stay flexible by a day or two, and check both ORD and MDW before you buy. Tuesday and Wednesday departures usually cost less than Friday or Sunday. Booking roughly one to three months ahead tends to hit the sweet spot for domestic trips.

Below are seven practical ways to find cheap airline tickets from Chicago and back home again. At EzeeFlights, we let you search more than 500 airlines in one place, so several of these tips take seconds to test. Each tip is something you can apply on your very next search, whether you are flying out for a weekend or heading in for business.

1. Compare fares across airlines with EzeeFlights

How it works

Start with one search instead of ten. EzeeFlights pulls fares from 500+ airlines into one results page, so you see prices side by side instead of opening a new tab for every carrier. The routine is simple:

1. Enter your departure and arrival cities, such as Chicago to Denver, plus your dates.
2. Sort by price, then re-sort by shortest travel time.
3. Compare nonstop and one-stop options on the same day.
4. Check the days on either side of your date before you pay.

Do not stop at the lowest number on the screen. A fare that is $25 cheaper but adds a four-hour layover or a checked bag fee is not a deal. Look at the total trip cost and travel time together, then decide.

Why it helps on Chicago routes

Chicago is one of the most competitive air markets in the country. United and American run large operations at O'Hare, Southwest is strong at Midway, and carriers like Spirit, Frontier, and Delta fight for the same passengers on popular routes. With that many airlines on one city pair, the cheapest carrier changes from week to week. Check one airline's site and you see one price. Compare them all and you see the gap.

The cheapest airline on your Chicago route this month is rarely the cheapest next month, so compare every time you search.

The same logic applies when you hunt for cheap airline tickets to Chicago IL. Inbound fares into ORD and MDW can differ by carrier and by day, so run the return search separately instead of assuming both directions price alike. Sometimes the best round trip pairs two different airlines, which a single-airline site will never show you.

Best for

This approach suits price-conscious travelers who want a quick read on the market before committing. If you are planning a weekend getaway, visiting family, or booking a work trip on short notice, one comparison search tells you what a fair price looks like in minutes.

It also works well as your first step before using the other six tips here. Run the broad search, note the best fares, and then narrow by airport, date, or airline.

2. Compare O'Hare, Midway and Rockford

How it works

Run the same trip once per airport code. Search ORD, then MDW, then RFD, keep your dates identical, and note the lowest fare for each. Before you pick a winner, add the ground transport cost to and from each airport.

Airport	Code	Known for	Watch out for
O'Hare	ORD	Widest network, United and American hub	Longest trip from some neighborhoods
Midway	MDW	Southwest, shorter security lines	Fewer international routes
Rockford	RFD	Low-cost leisure flights	About 75 miles from downtown

Why it helps on Chicago routes

Each airport has a different airline mix, so the same route can price very differently depending on where you fly from. Southwest drives competition at Midway, while O'Hare has the most nonstop options and the most carriers fighting over the same passengers. Rockford is smaller, but it has low-cost leisure service to places like Florida and Las Vegas that can undercut the big two.

The cheapest Chicago fare often hides at the airport you did not search.

This matters for cheap airline tickets to Chicago IL as well. Flying into Midway instead of O'Hare can save money if your hotel or family sits on the south or west side. Rockford only makes sense when the fare gap is large enough to cover the long drive or bus ride.

Best for

This tip suits flexible travelers who live in the city or suburbs and can reach more than one airport without much trouble. It also helps if you are heading to a popular leisure destination, where low-cost carriers compete hardest.

Skip Rockford if you are short on time or traveling with a lot of luggage. For most people, the real contest is O'Hare versus Midway, and a two-minute check of both is worth it every time.

3. Fly in the cheapest months and on midweek days

How it works

Airfares follow demand, so pick dates when fewer people want to fly. Shift your trip by a few days and compare. Tuesday, Wednesday, and Saturday departures usually cost less than Friday or Sunday, when leisure and business travelers crowd the planes. The same goes for off-peak months.

Period	Typical fare level
January to early March	Lowest into Chicago
September to mid-November	Low to moderate
June to August	Highest, peak summer
Thanksgiving and December holidays	High everywhere

Why it helps on Chicago routes

Chicago winters are cold, so demand into the city drops after the holidays. Flights into ORD and MDW from January through March tend to be cheap, and hotels follow. If you want cheap airline tickets Chicago visitors rarely find in July, aim for that stretch.

Move your Chicago trip by a couple of days or a few weeks, and the same route can cost noticeably less.

Outbound travel works differently. Flights from Chicago to Florida or Arizona fill with winter escapees, so shoulder months like late April or October often beat February. Summer adds its own spikes, including big festival weekends such as Lollapalooza in early August. Check the city calendar before you lock dates for a trip to Chicago.

Best for

This tip suits remote workers, retirees, and anyone with flexible time off. You can fly on a Tuesday and stay through the next Tuesday without losing a workday.

If your dates are fixed for a wedding or school break, you still have a lever. Move just one leg to a midweek day and compare the total against flying both ways on a weekend.

4. Book at the right time before departure

How it works

Fares move as seats sell. Airlines open with a mix of prices, then raise them as the plane fills and departure gets close. Your goal is to buy after the early, untested pricing and before the last-minute climb. Use these windows as a starting point:

Trip type	When to book
Domestic, to or from Chicago	1 to 3 months out
International	2 to 6 months out
Thanksgiving, Christmas, summer peaks	3 to 5 months out
Inside 14 days	Expect the highest prices

Search your route a few times over a week to learn its normal range. When a fare lands at or below that range, book it instead of chasing a bigger drop.

Why it helps on Chicago routes

Chicago is a high-volume market, so carriers reprice constantly as United, American, Southwest, and the low-cost airlines react to each other. A fare you see today can be gone tomorrow, which makes waiting a real gamble on busy routes.

Book inside the one-to-three-month window, and stop waiting for a price drop that rarely comes.

Peak dates need even more lead time. Winter holiday flights out of O'Hare and summer festival weekends fill early, so book those trips in the fall or spring to avoid the surge. Off-peak midweek flights give you more room to wait, but the same rule holds for cheap airline tickets to Chicago IL: once the price looks fair, lock it in.

Best for

Anyone with fixed dates and time to plan gets the most from this tip. That includes holiday travelers, wedding guests, and families coordinating school breaks. If your trip is still more than three months away, start tracking prices now and buy once you reach the window.

Last-minute travelers can still save money. Combine this tip with flexible dates and nearby airports to soften the late-booking premium.

5. Target low-cost carriers like Southwest and Frontier

How it works

Low-cost carriers win you over with a low base fare, then charge for extras. Your job is to compare the all-in price, not the headline number. Before you book, add up these costs:

• Carry-on and checked bag fees
• Seat selection
• Change and cancellation rules
• Airport transfer cost

Southwest has changed its bag and ticket policies in recent years, so read its current rules instead of trusting old advice. Frontier is stricter still. A $49 fare can pass a $120 fare once you add a bag and a seat.

Why it helps on Chicago routes

Southwest runs a major operation at Midway, and its presence forces other airlines to match or undercut prices on popular routes. Frontier flies out of O'Hare and goes after leisure travelers with bargain fares that United and American often have to answer. Rockford adds Allegiant, which serves vacation spots at low prices.

A low-cost carrier is only cheaper if the fare still wins after bags and seats are added.

This helps when you search for cheap airline tickets Chicago travelers can actually keep under budget. Leisure routes such as Las Vegas, Orlando, Phoenix, and Denver tend to show the biggest gaps. Always run the same search with the big carriers too, because a legacy airline sometimes wins once extras are counted.

Best for

This tip fits carry-on-only travelers, such as weekend flyers and solo vacationers who can pack a personal item and a small bag. It also suits anyone who can handle a tighter schedule, since low-cost carriers run fewer flights per day.

Skip it if you are bringing checked luggage, sports gear, or kids with car seats, or if you need easy rebooking. In those cases a traditional carrier's fare often comes out even or lower.

6. Price one-way tickets and mix airlines

How it works

Most search tools default to round trip, but a round trip is not always the cheapest way to travel. Price each direction on its own, then compare the sum against the bundled fare. Let the outbound and return legs choose different airlines if that is cheaper.

1. Search the round-trip fare and write down the total.
2. Search the outbound leg as a one-way.
3. Search the return leg as a one-way.
4. Add both prices plus bag fees for each airline, then compare.

Why it helps on Chicago routes

Chicago has so many carriers that the best outbound and return fares often come from two different airlines. Southwest and Frontier tend to price each direction separately, so their one-way fares rarely carry a penalty. That lets you fly out on Southwest from Midway and come home on United into O'Hare.

Two one-way tickets can beat one round trip, but only the combined total tells you which.

This is a strong move when you hunt for cheap airline tickets Chicago travelers can pair across carriers. Keep one risk in mind. Separate tickets are not protected against each other, so a delay on the first flight will not rebook the second. Also confirm which airport each leg uses, so you do not land at O'Hare and leave your car at Midway.

Best for

This tip suits carry-on-only travelers who can fly any airline without worrying about bag fees on each leg. It also helps one-way trips, such as a move, a college drop-off, or an open-ended stay.

Avoid it if you have a tight connection or an international leg that depends on the first flight arriving on time. In those cases, a single ticket costs a little more but protects your trip.

7. Stay flexible with flexible dates and destinations

How it works

Flexibility makes every other tip on this list work harder. Instead of searching one date and one city, widen your search and let the fares point you to the deal. Try these moves:

• Shift your departure and return by one to three days either way.
• Compare the weekend before and after your first choice.
• Search several destinations that fit the same trip, such as Phoenix, Las Vegas, and San Diego for a sunny escape.
• Book the cheapest pairing of date and destination.

A calendar or multi-day view on EzeeFlights shows these price swings quickly, so you can compare dates side by side without re-entering your search.

Why it helps on Chicago routes

Because O'Hare and Midway serve so many cities, you almost always have several comparable destinations at very different prices. If all you need is warm weather, a mountain weekend, or a visit to a big city, the fare can pick the winner. Opening your search this way is how you find cheap airline tickets from Chicago that a fixed plan never uncovers.

The more you let the fare decide, the less you pay.

The same applies when you hunt for cheap airline tickets to Chicago IL. Moving a visit by a few days to dodge a convention week or a big concert can lower both your airfare and your hotel bill. Check the city event calendar, then search the dates around it.

Best for

Travelers whose goal is a trip, not one specific place, gain the most. Think vacationers, couples planning a getaway, and friends who just want a few days away. Flexible work schedules help too, since you can leave when prices dip.

Skip this approach if you are attending a wedding, a funeral, or a fixed business meeting. In those cases, keep your dates and destination fixed and use the other six tips, especially airport comparison and booking timing, to bring the price down.

Putting it all together for your Chicago trip

Finding cheap airline tickets Chicago travelers can trust comes down to a short routine. Compare many airlines at once, check O'Hare, Midway, and Rockford, and move your dates toward midweek and off-peak days whenever you can.

Then book inside the one-to-three-month window, judge low-cost carriers by their all-in price, and test one-way tickets on different airlines. Stay flexible on dates and destinations, and the fare does most of the work for you. Use the tips that fit your trip and skip the ones that do not.
