Frequently asked questions

Is it cheaper to buy a plane ticket from El Paso Intl. Airport to Washington Dulles Intl. Airport (IAD) last minute?
Booking your flight from ELP to Washington Dulles Intl. Airport (IAD) at the last minute could save you a tidy sum if you strike it lucky and find an amazing deal.

If you don’t want to hedge your bets, book well ahead of the date you want to leave. In fact, you can find some of the biggest deals up to a year in advance. If your preferred carrier hasn’t released its fares yet, check back regularly as offers are constantly updated on Expedia.
