Frequently asked questions

Is it cheaper to buy a plane ticket from O'Hare Intl. Airport (ORD) to Los Angeles - Ontario Intl. Airport (ONT) last minute?
Booking your flight from O'Hare Airport to Los Angeles - Ontario Intl. Airport (ONT) at the last minute could help you save if you get lucky and find an awesome deal. However, tickets don't usually get cheaper as the departure date nears. If you take a wait-and-see approach, flights could also be booked out or the best seats gone (that could mean the middle seat!). If you'd rather not hedge your bets, book well ahead of your departure date. In fact, Expedia has some of the biggest deals up to a year in advance. If your preferred airline hasn't released its fares yet, check back regularly as deals are updated on Expedia constantly.

Can I change the date of my flight from ORD to Ontario Airport?
You can easily make changes to your ORD to ONT flight via the Expedia Trips portal.
