Top tips for finding a cheap flight out of Chicago O'Hare International Airport (ORD)

Book in the Goldilocks Window

To get the best deal on a domestic flight, we recommend booking 1-3 months before your trip. For an international trip, it’s 2-8 months in advance. We call this the Goldilocks Window. It’s the time that’s not too far in advance, but not too last minute, when great deals are most likely to pop up.

However, if you can't be flexible with your travel dates or are traveling in peak season, we suggest booking even further ahead. For example, if you’re looking to travel over the December holidays, start keeping an eye out in July.

Once you get to about a month out, prices are almost guaranteed to rise, especially at the 21-day, 14-day, and 7-day points, so try to book before those if possible.

Use the Greek Islands Trick

If the place you want to fly is pricy, look at fares that get you close to where you want to go. Let’s say you want to fly from Chicago to Santorini in June, but tickets are $1,200 roundtrip. Consider, instead, flying to London for $500 roundtrip. From there, a flight to Santorini could be under $200. We call this the Greek Islands Trick, but it works equally well for many other destinations.

Focus on finding the cheapest flight you can that gets you close to where you want to go, then buy a separate flight (or train or ferry ticket) that closes the gap. It requires a bit more effort and planning, but the savings can be huge.

Search nearby—and not so nearby—airports

If you live in Chicago, you’re probably already in the habit of looking for flights not just out of O’Hare, but out of Midway as well. But sometimes, it can make sense to check out flights from airports outside of your city. While typically O’Hare will have better deals than, say, Milwaukee, it’s always good to compare. Sometimes the airlines do wild things and drop prices out of unexpected cities. When looking at long-haul flights, it can sometimes even make sense to look at flights departing airports farther away from home.

If you live in Chicago, why on earth would you look at flights out of LA, Miami, or NYC? Well, sometimes other cities have spectacular deals that are worth the connecting flight. We’re talking about once-in-a-lifetime kind of deals. Like $63 from Atlanta to Chile roundtrip. Or $202 from Los Angeles to Japan. For that price, even if you add a $200 flight from Chicago to LA, you still come out ahead.

Fly when it’s cheaper

As with most of the world, summer is a peak season for travel. Kids are out of school. The weather is warm. People have more flexibility. So it's no surprise many vacationers like to travel during the summer. But with high demand comes even higher price tags. Shoulder season, the time in between the peak and low travel times, offers the best opportunity to save money. When you plan your next trip, look at the best times to travel. Then, plan your trip closer to the start or end of those peak season dates. Or go completely off the cuff and see what the world is like when it isn't full of tourists.

If you’re limited on when you can travel in terms of season, at least try to fly on cheaper days. Tuesday, Wednesday, and Saturday are the cheapest days to fly. Friday and Sunday are usually the most expensive days.

Set alerts for specific trips

One of the easiest ways to stay on top of the constant changes in airfare is by setting up a fare alert. You'll then get an email when the price on any itinerary you're tracking drops to a specific range. And, if you set up these alerts several months before you plan to travel, you'll have a better chance of recognizing a good deal when you see it. If you're keeping your dates or locations flexible, however, you would need to set up multiple fare alerts.

How early should I arrive to Chicago O’Hare International Airport (ORD) before my flight?

Most airlines recommend you arrive at the airport two hours before a domestic flight and three hours before an international flight. But whether you really need to be there that early depends on a number of factors.

How big is the airport, and where is your gate? O’Hare is pretty large, and the walk from security to some of the farthest gates can take 15-20 minutes. If you’re arriving via the Blue Line, you’ll also need to add some extra time for walking from the train terminus to security; this takes about five minutes on average.

Are you checked in? Every airline has a check-in cutoff, typically 30-60 minutes before departing. If you can’t check in online, you’ll need to arrive at the airport before this cutoff time.

Are you checking luggage? Similarly, every airline has a cutoff time after which they will not accept checked luggage. Typically this is 45-60 minutes before the flight.

How busy is the airport? On an average day, the security wait at O’Hare is about 10-15 minutes. But if you’re traveling around a holiday, during summer, or on busier days like Friday and Sunday, it can be much, much longer. At these times, it’s better to err on the side of arriving early.

At the bare minimum, it’s wise to arrive at O’Hare at least one hour before your flight, but 1.5-2 hours is a safer bet on most days. During peak times, 3-4 hours in advance may be necessary.

How far is Chicago O’Hare International Airport (ORD) from downtown Chicago?

Chicago O’Hare International Airport (ORD) is 17-20 miles from downtown Chicago, depending on where in the city you’re departing from.

What are the different transportation options for going from the city center to Chicago O’Hare International Airport (ORD)?

  • By taxi or ride share: Downtown Chicago is less than 20 miles from the airport, and you can get there by car in about 30 minutes with no traffic, though we suggest allowing at least 45 minutes at most times. Costs range from about $35-$50, depending on demand.
