FAQs about Washington Dulles Intl. Flights

Flying Tips & Tricks How do I find my flight number?
  • Your flight number is contained in your itinerary. It's a series of numerals and letters, and it should be easy to find.
How early can you check bags for a flight?
  • To have plenty of time to drop your bags, clear security and customs and arrive at the correct boarding gate, head to the airport approximately three hours before an international flight. If you're traveling domestically, it's two hours. Even if you've already chosen your seat and downloaded your boarding pass at home, it's worth keeping in mind that there are closing times for baggage check-in. It's one hour before departure for international flights, and 45 minutes if you're traveling domestically. Of course, times can vary between airlines, so it's wise to check these details when you book.
