International travel

Whether you’re about to leave the country for the first time or you’re used to traveling internationally, you may have questions. Here are some helpful links and destination information to help you prepare for your trip.

General information

  • International travel document requirements

    Before your next international trip, make sure you have all the required documents for departure and arrival. You may need to meet these special requirements even if you’re traveling through the country on a connecting flight and not leaving the airport.

    You can search by destination to learn about passport, visa and health requirements for specific countries. This information is from the International Air Transport Association.

  • U.S. passport application processing times

    The U.S. Department of State recommends that U.S. citizens submit passport applications and renewals at least 10 weeks before their travel.U.S. citizens can no longer receive passport page inserts, so if you're running out of pages, you may want to renew now even if your passport isn’t expiring.

    For information on how to apply for or renew a passport, go to the U.S. Department of State's Passport page.

  • Yellow fever vaccination

    If you’ve traveled to a country in the epidemic zone for yellow fever in the last 30 days, you may need the yellow fever vaccine before you take other international flights. If the vaccination is required by the country you’re traveling to, you’ll need to show a vaccination certificate issued at least 10 days before your arrival in that country. Find passport, visa and health requirements by destination.

  • ESTA for Visa Waiver Program travel to or through the U.S.

    The U.S. Department of Homeland Security requires Visa Waiver Program travelers to get approval from the Electronic System for Travel Authorization (ESTA). If you’re traveling without a U.S. passport and need an ESTA, we recommend applying when you book your travel and at least 72 hours before you travel. For more information, visit the U.S. Department of Homeland Security's ESTA website. ESTA requirements can change, so you may want to check U.S. Department of Homeland Security press releases before you travel.

  • Centers for Disease Control and Prevention (CDC) travel health notices and other travel advisories

    The CDC issues travel notices to help make travelers aware of health concerns around the world. Visit the CDC website for country-specific health information.

    The U.S. Department of State also gives updates on other issues, such as crime or civil unrest, that travelers may need to be aware of before traveling to a certain country. For the latest travel advisories, visit the U.S. Department of State website.

  • U.S. Customs and Border Protection’s biometric matching service

    At certain airports we are partnering with U.S. Customs and Border Protection (CBP) to test their biometric matching service during our boarding process for select United international flights departing from the U.S. If a customer chooses to participate in this boarding alternative, CBP will compare the customer’s picture to existing images CBP already has from U.S. passports, U.S. visas, and previous entries into the U.S.. Customers verified by CBP are able to board their flight without a boarding pass.

    This test program is optional. Customers should see an agent with any questions or if they do not want to participate in this optional boarding alternative.

    United does not store customer pictures in connection with this test program. CBP compares the customer’s picture to images CBP already has. CBP stores the customer’s picture as described at
