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 https://www.cbp.gov/travel/biometrics.
Certain countries require aircraft cabins to be treated with insecticides. For more information and a list of those countries, visit the U.S.Department of Transportation's disinsection website.
