Is it cheaper to buy a plane ticket from IAD to Athens International Airport last minute?
Booking your trip from IAD to AIA Airport at the last minute could save you a pretty penny if you luck out and find a bargain. However, tickets don’t typically get cheaper as the date of departure nears. If you take a wait-and-see approach, flights could also be booked out or the best seats gone (that could mean the middle seat!). If you don’t want to risk it, book well in advance of the date you want to leave. Note that some of the biggest deals can be found up to 12 months in advance. If your favorite carrier hasn’t released its airfares yet, check back regularly as offers are constantly updated on Expedia.

What are the most popular departure times for flights from Dulles Intl. Airport to AIA Airport?
The most popular departure times for journeys from Dulles Intl. Airport to ATH are between 5:00 PM - 6:00 PM on United Airlines. Our advice is to jet off in the morning. The earlier you travel, the better your odds of a delay-free flight as air traffic hasn’t yet built up.
