Currently, a plane ticket to Oak Brook, Chicago is approximately $121.25 (remember, that's one-way only). After crunching the data for rates and flight routes from all over, we've found the cost to fly to Oak Brook to be one of the cheapest, a real perk for people who need to get there.
It's important we mention that this may not necessarily mean that $121.25 is the absolute best price you'll find from Expedia, but it is a good place to start. That fare is dependent on a lot of different factors such as the airline, the airport you leave from, and others.
For example, we have found that travelers who book accommodations and airfare together may save up to 570 dollars.* Likewise, by just bundling the plane ticket and rent-a-car together, you can save as much as 60%!**
Whether you are just exploring the local city or expect to experience all of the greater Chicago area, we wish you well on your adventure.
