Frequently asked questions

Is it cheaper to buy a plane ticket from LAX to Ontario Airport last minute?
When it comes to booking your flights, it pays to be prepared. While it's possible to pick up a last-minute deal on a LAX to ONT flight, fares usually don't get cheaper as the departure date nears. Based on flight pricing and demand studies in 2022, we have found that the sweet spot to book a domestic flight is between 28 – 35 days ahead. For international travel it's three to four months.
What airports do you fly into for Ontario from Los Angeles?
From Los Angeles, you can get to Ontario via Los Angeles - Ontario Intl. Airport (ONT), John Wayne Airport (SNA) and Long Beach Municipal Airport (LGB). It's wise to check which terminal is right for you before you make a decision. If you decide to land at Los Angeles - Ontario Intl.

You can quickly make changes to your LAX to ONT ticket through the Expedia Trips portal.
