  • Osaka airport: Schedule and facility updates

    United flights to and from Osaka have resumed normal operation following Typhoon Jebi.

    As the transportation access to the airport is limited, significant congestion is expected. Please arrive at the airport with plenty of time to spare. You can check the latest information on the airport access at the Kansai International Airport website.​

  • Additional security measures for international flights to the U.S.

    The U.S. Department of Homeland Security (DHS) requires additional security measures for all international flights to the U.S., which may result in extra screening for everyday items such as powder, food, books, magazines and large electronics.

    Per the DHS, beginning June 30, 2018, some travelers may also be subject to additional security measures to prohibit powder-based substances greater than what would fit in a standard soda can (12 fluid ounces or 350 milliliters) packed in carry-on bags and personal items. If the substance is in excess of the allowed amount, it won’t be permitted in the cabin of the aircraft. There are some exemptions, including baby formula, medically necessary powder and human remains.

    Please note that some foreign governments who perform this screening at the central checkpoint may follow more strict measures, including confiscating and disposing of powder-based substances in excess of permitted quantities.

    We recommend all customers place any items that resemble powder in checked baggage to avoid any disruption to travel.

    The Transportation Security Administration (TSA) recommends arriving at the airport at least three hours before your international flight, if possible, to allow time for the additional security measures. Be sure to view the airport check-in hours first.

    For more information, please visit the DHS website. You may also contact @AskTSA via Twitter or Facebook Messenger with specific questions or visit TSA customer service.

  • ​Traveling on flights precleared by U.S. Customs and Border Protection​​​​

    Customers traveling on international flights that are precleared by U.S. Customs and Border Protection (CBP) should arrive well before the minimum required time. When customers travel on a U.S. CBP precleared flight, they will arrive at a domestic terminal in the U.S. Customers should allow extra time at the international airport they are departing from to complete additional border security screening processes before departure.

    United Airlines operates flights precleared by U.S. CBP before departure from the following international airports:

    • Aruba International Airport (AUA)
    • Bermuda L. F. Wade International Airport (BDA)

    Signs in the terminals and near entrances to Air Transit System platforms will provide directions to bus stop locations. You can also find more information on the Chicago Department of Aviation website.​​

  • San Francisco Airport’s AirTrain overnight closures

    San Francisco International Airport’s AirTrain service is currently closed overnight weekdays from 8 p.m. to 5 a.m. During these closures, the airport will operate buses between all terminals and the Rental Car Center. The AirTrain will operate with modified service on weekends from 10 p.m. to 5 a.m.

    Buses will pick up and drop off travelers on the center island of the departure level for all terminals and operate more frequently.

    The airport advises travelers to allow extra time during the closures.​

  • Additional TSA screening of perishable items at San Juan (SJU)​

    TSA has implemented additional security measures at Luis Muñoz Marín International Airport (SJU) that require all wet or frozen food items to be removed from carry-on baggage and inspected. While food items are permitted in carry-on baggage, travelers departing San Juan are advised to allow extra time at security or to check bags containing wet or frozen food items to expedite the screening process. This policy applies to standard screening lanes but does not affect TSA Pre✓® lanes.

  • Important information about U.S. IDs​​​

    Beginning October 10, 2018, U.S. driver’s licenses or state IDs that are not in compliance with the REAL ID Act and have not been granted an extension cannot be used as identification when flying within the U.S
