Is it cheaper to buy a plane ticket from ONT to Washington Dulles Intl. Airport (IAD) last minute?
Booking your flight from Ontario Airport to Washington Dulles Intl. Airport (IAD) at the last minute could save you a tidy sum if you happen to find an awesome deal.

If you'd rather play it safe, book well in advance of the date you want to leave. Don't forget that some of the biggest bargains can be found up to a year in advance. If your favorite airline hasn't released tickets yet, check back regularly as deals are constantly updated on Expedia.
