Frequently asked questions

Is it cheaper to buy a plane ticket from Houston Airport to Ontario Airport last minute?
Being the spontaneous type is a great way to explore the globe, but it's not necessarily the wisest way to pick up a cheap fare. Consider booking your Houston Airport to Ontario Airport trip ahead of time instead of leaving it until 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. We recommend saving that spontaneity for when you arrive in Ontario Airport!
What airports do you fly into for Ontario from Houston?
Los Angeles - Ontario Intl. Airport (ONT), John Wayne Airport (SNA) and Long Beach Municipal Airport (LGB) are your options when setting off from Houston to Ontario. About 5 kilometers east of the heart of Ontario, Los Angeles - Ontario Intl. Airport (ONT) is the city's main gateway. Consider factors like flight departure and arrival times and the distance to your hotel before deciding where you fly into. Ontario Mills Shopping Mall and Toyota Arena are two top attractions to add to your must-see list when you arrive.
