Frequently asked questions

Is it cheaper to buy a plane ticket from Los Angeles - Ontario Intl. Airport (ONT) to Roberts Field last minute?
Booking your flight from ONT to Robert’s Field Airport (RDM) last minute could save you dollars if you happen to find an amazing deal. However, tickets typically don’t come down in price as the date of departure nears. If you take a wait-and-see approach, flights could also be sold out or the best seats taken (because who wants the middle seat?). If you’d prefer to play it safe, book well ahead of when you want to leave. Keep in mind that some of the best deals can be found up to a year in advance. If your favorite carrier hasn’t released its airfares yet, check back regularly as offers are constantly updated on Expedia.
