Frequently asked questions

Is it cheaper to buy a plane ticket from ONT to OCW last minute?
Being the spontaneous type is a fantastic way to explore the globe, but it's not always the smartest method to score a cheap airfare. It's better to book your ONT to Washington-Warren Field Airport trip well in advance 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 get to Washington-Warren Field Airport!
What airports do you fly into for Washington from Ontario?
From Ontario, you can connect to Washington through Warren Field Airport (OCW), Pitt-Greenville Airport (PGV) and Craven Regional Airport (EWN). Research which hub is more convenient for you before making your decision. If you go with Warren Field Airport (OCW), it's about 3 kilometers north of the center of the city. Use the dough you save when booking your trip with Expedia to experience the city's awesome attractions, such as Washington Square Mall and Cypress Landing Golf Club.
Can I change the date of my flight from ONT to OCW?
You can quickly and easily make changes to your Ontario Airport to Warren Field Airport (OCW) flight via the Expedia Trips portal. But before doing so, read the conditions in your itinerary to see what the carrier will allow you to do and if change fees apply.
