Airport updates

Payment transactions at airports

United continues to introduce new technology in support of a faster and more efficient travel experience. As part of these efforts, the United check-in counters and kiosks at some of the airports we serve do not accept cash as a form of payment. Customers at Chicago O'Hare, Cleveland, Denver, Houston Intercontinental, Los Angeles, New York/Newark, San Francisco, Seattle and Washington Dulles can use ReadySTATION™ kiosks free of charge to convert up to $1,000 in cash to a Visa® prepaid card, which they can use to pay for baggage service charges or other purchases at an airport kiosk or check-in counter. These prepaid cards are also valid for other transactions completed with any vendor that accepts Visa.

International travel

  • Reciprocity fee for travel to Argentina

    American, Australian and Canadian citizens are now required to pre-pay a Reciprocity Fee for entry into Argentina. In the past, the fee was collected at Argentine airports upon arrival; however, customers must now pay the Reciprocity Fee online through Argentina's National Immigration Agency website before checking in for their flight to Argentina. A barcoded receipt for payment must be presented to a representative at check-in.

    United is not permitted to transport to Argentina any American, Australian, or Canadian citizen who has not paid the Reciprocity Fee prior to departure. Failure to provide a copy of the barcoded payment receipt at check-in will result in a delay or possible denial of your travel to Argentina. Please visit www.migraciones.gov.ar for complete details, including the fee amount and the validity period. Any questions regarding this fee or the payment process should be directed to the Argentine authorities.

  • Travel to Venezuela
    The Secretary of the U.S. Department of Homeland Security is unable to determine whether Venezuelan airports that serve as the last point of departure for non-stop flights to the U.S. maintain and carry out effective aviation security measures in accordance with the Standards and appropriate Recommended Practices established by the International Civil Aviation Organization (ICAO). All flights are subject to continuing effectiveness of government approvals.

  • ESTA for U.S. Visa Waiver Program Travelers
    The United States Department of Homeland Security requires Visa Waiver Program travelers to obtain approval from the Electronic System for Travel Authorization (ESTA) prior to check-in for a flight to the U.S. or connecting through the U.S. Learn more about ESTA

    To apply for authorization to travel to the U.S., travelers may go to the ESTA web-based system and complete an application.

  • U.S. Departure and Entry Requirements
    U.S. federal legislation requires all customers, regardless of citizenship or age, to hold a valid passport for travel by air to or from the U.S. Review the complete details.

    Passport, visa and health requirements for the transit and destination countries are provided by the International Air Transport Association (IATA) on united.com as a courtesy and should be verified by the passenger before travel. Remember that if the passenger is departing the U.S., a passport is now required, regardless of the destination country's entry requirements.

    U.S. federal legislation requires commercial air carriers operating international flights to the U.S. to submit the visiting address of all passengers who are non-U.S. citizens and non-residents to U.S. Customs and Border Protection before travel commences. Customers will be expected to provide this information during check-in.
