Practical Tips for United Travelers at Dulles

1. Arrive Early and Be Prepared

  • Domestic Flights: 2 hours before departure helps account for security lines, especially during peak times.
  • International Flights: 3 hours or more is recommended because of extended security and immigration checks.

2. Check Your Gate in Advance

  • United’s flight status page and the airport’s real‑time board show gates that may change due to weather or operational considerations. Download the United app for push notifications about gate changes.

3. Pack Smart

  • Baggage Allowance: 1 carry‑on and 1 checked bag for economy (balanced by U.S. rules). Extra fees apply for overweight or additional items.
  • Security Rules: Remember the 3‑1‑1 liquid rule for carry‑ons and the TSA’s new “TSA PreCheck” options if you’re eligible – United to IAD already offers TSA PreCheck enrollment.

4. Use the United Mobile App

  • Boarding Pass: Digital storage reduces paper waste.
  • Seat Selection: Reserve preferred seats (including extra legroom options) for a small fee.
  • Flight Alerts: Real‑time updates on delays.

5. Lounge Access

  • United Polaris: For international premium passengers, free access even for economy flyers if you hold a travel insurance plan that partners with United.
  • United Club: Membership or credit‑card partners (e.g., United Explorer® or Chase Sapphire®). Non‑members can purchase entry for a flat fee.

6. Take Advantage of Pick‑up Transport

  • The United Aviation Center at Dulles offers free pick‑up shuttles to the airport from the boarding gate area, which some travelers find convenient.
