Frequently asked questions

Is it cheaper to buy a plane ticket from Midway Intl. Airport (MDW) to ONO last minute?
Being a spontaneous soul is an awesome way to discover the world, but it's not always the wisest way to find a bargain flight. Consider booking your MDW to ONO journey well in advance instead of waiting till the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. Leave all that spontaneity for when you get to ONO!
What airports do you fly into for Ontario from Chicago?
There are two options when jetting from Chicago to Ontario — Ontario, OR (ONO-Ontario Municipal) and Boise Airport (BOI). If you land at Ontario, OR (ONO-Ontario Municipal) you'll be approximately 11 kilometers north of the center of Ontario. Check in to your hotel, then head out and explore the local sights!
