Frequently asked questions

Is it cheaper to buy a plane ticket from Dulles Intl. Airport to ALT last minute?
Being the spontaneous type is an amazing way to see the world, but it's not necessarily the smartest way to land a bargain plane ticket. Consider booking your Washington Dulles Intl. Airport (IAD) to ALT journey well ahead of time instead of waiting till the last minute. Based on flight pricing and demand studies in 2022, we have found that the best time to book domestic flights is between 28 – 35 days ahead of the departure date, and international flights three to four months in advance. Save up that spontaneity for when you arrive in ALT!
Can I change the date of my flight from IAD to ALT?
Quickly make changes to your Dulles Intl. Airport to ALT flight via the Expedia Trips portal. But before amending dates or times, read over the rules and restrictions in your itinerary to learn what you're allowed to do and what charges may apply. Some carriers charge a change fee per person, in addition to any difference in fares. But if you booked in the last 24 hours, you may be able to cancel for free and arrange new flights.
