Frequently asked questions

Is it cheaper to buy a plane ticket from Buffalo Niagara International Airport to Los Angeles - Ontario Intl. Airport (ONT) last minute?
Booking your flight from Buffalo Niagara Intl. Airport (BUF) to ONT at the last minute could save you a pretty penny if you strike it lucky and find a bargain.

If you'd rather err on the side of caution, book well in advance of when you want to leave. In fact, some of the best deals are available on Expedia up to 12 months in advance. If your favorite airline hasn't released tickets yet, check back regularly as offers are updated on Expedia constantly.
