FAQs about Washington Dulles Intl. Flights

Flying Tips & Tricks How do I find my flight number?
  • You'll find a code somewhere in your travel itinerary, which you'll receive when you've completed your booking. Just keep your eyes peeled for the IATA airline code (which consists of a couple of letters and a single digit) followed by one, two, three or four digits — your flight number.
How early can you check bags for a flight?
  • For international flights, check-in and luggage drop open around three hours before departure and close one hour prior to takeoff. For domestic flights, check-in and luggage drop open two hours before departure and close 45 minutes prior to departure. These times can vary between each airline, so be sure to check before you travel.
