Frequently asked questions

Is it cheaper to buy a plane ticket from ONT to Kingsford Smith Intl. Airport (SYD) last minute?
Being a spontaneous soul is a great way to explore the globe, but it's not necessarily the best method to land a cheap plane ticket. Think about booking your Los Angeles - Ontario Intl.

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. We recommend saving that spontaneity for when you get to your destination!
