Frequently asked questions

Is it cheaper to buy a plane ticket from ILG to Los Angeles - Ontario Intl. Airport (ONT) last minute?
Booking your trip from ILG to ONT at the last minute could save you a nice sum if you strike it lucky and find a terrific deal. However, tickets generally don't get cheaper as the date of departure nears. If you choose to wait, flights could also be booked solid or the best seats gone (that could mean the middle seat!). If you'd rather play it safe, book well in advance of when you want to leave. Keep in mind that some of the best deals can be found up to 12 months in advance. If your preferred carrier hasn't released its fares yet, check back regularly as offers are constantly updated on Expedia.
