​## Practical Tips for Travellers at Dulles

H3: Navigating the Terminals

  1. Check Which Terminal Your Airline Uses – United and American use Terminal 1, while JetBlue and Alaska are in Terminal 6. International travelers often start in Terminal 3, then move to the SkyGate portion of Terminal 5 for security.
  2. Use the Airport Shuttle – Dulles offers complimentary travel centre shuttles that run every 10 min between terminals. Look for the blue “Travel Centre Shuttle” signs.
  3. Set a Time Buffer – Because transfers between terminals can take 15–20 min, schedule an extra 30 min if you’re switching from domestic to international flights.

H3: Security & Border Control

  • Global Entry & TSA PreCheck: Pre‑approved travelers save X minutes. Apply via the official TSA website and select “Dulles IAD” as your preferred airport.
  • People‑Mosaic Check: Dulles’ AI‑powered system may require a quick additional ID check. Stay calm and follow staff instructions.

H3: Dining and Lounges

  • American Airlines Admirals Club – Near gate 45, 48 % discount rates for members and non‑members.
  • Delta Sky Club – Adjacent to Terminal 1’s domestic concourse; great for an espresso before the flight.
  • International Lounges – Business Class passengers from Air France, Emirates, and Qantas have dedicated areas. Quick glimpses at both lounges can be achieved via the SkyGate walkway.

H3: Booking Tips

  1. Compare Airlines via Aggregators – Use Google Flights, Kayak, or Skyscanner to view price curves for 3–4 months before booking.
  2. Look for “Clearance” Nights – Some airlines offer discounted “flight clearance” passes (e.g., United’s Southwest “SkyScan”). These are flights without excess baggage fees and can yield savings.
  3. Join Frequent Flyer Alerts – Earn miles by signing up for free signals on Miles & Rewards. Many airlines send flash deals to supporters.

H3: Checking Flight Status

  • Dulles’s real‑time flight tracker connects to your flight number. Install the IAD Airport & Airlines Now! App for push notifications.
  • For flights that connect to another major hub, get ARP (Arrival/Departure) display copies.
