Manage reservations

Changing your flight

  • Reservations that are eligible to be changed can be changed online or through the mobile app by selecting “Change flight” from the reservation. You will see any applicable fare difference and/or change fees when you search for new flights. If your ticket is not eligible to be changed, you will receive a message when selecting “Change flight.”

  • Basic Economy tickets aren’t eligible to be changed. For more information, please visit the Basic Economy FAQs.

  • You may be eligible to change with United if your reservation was made by a travel agent or through another third party, however there may be a fee (in addition to the applicable change fee). We recommend first checking with the third party for change options.

  • You can switch to an earlier or later flight within 24 hours for a discounted fee if you are holding an eligible ticket depending on availability. Basic Economy tickets are not eligible for flight changes. MileagePlus Premier® Gold, Premier Platinum and Premier 1K® members may request a same-day change at no charge. For additional information, please visit the Same Day Change FAQs.

  • To change flights for a specific traveler, you can select the applicable traveler during the first step in the change path.

Canceling your flight

  • If your plans change and you prefer not to change your itinerary immediately, you may cancel the reservation and return to it to make changes for up to one year from the date of issue. A change fee may apply.

  • Award tickets may be subject to award service fees to redeposit miles, along with specific requirements for canceling tickets on partner airlines. More information is available on the Award Ticketing Options/Service Fees page.

  • To cancel flights for a specific traveler, you must divide the reservation which will create multiple individual reservations, and then cancel the applicable reservation. To divide the reservation, select the individual cancel option in the travelers section on the reservation.

Schedule changes, weather, delays or cancellations

  • When your itinerary requires rebooking because of a flight delay or cancellation, our automated systems will try to confirm you on the next available United flight. If you provided contact information during check-in, you'll receive an email or text message regarding your updated itinerary. For more information, please visit the Flight Delays and Cancellations page.

  • Most schedule changes are minor, but if your scheduled departure or arrival time changes by 30 minutes or more, we'll be happy to try to find other available flight options that meet your needs.

    If you want to explore other options, it’s important to know who to contact for assistance with a schedule change, and that depends on how you booked your flights:

    • Booked directly with United

      When viewing your reservation, you may be given the option to accept the changes online. If you don’t see an option to accept the new itinerary, or if your new itinerary doesn’t work for you, please call our United Customer Contact Center and we’ll be happy to help.

    • Booked through another airline or agency

      You should receive notification of the change from the airline or agency, and you should contact them for assistance.

  • When severe weather or other major events may impact our operations, we sometimes issue travel waivers to allow you to change to alternate flights without paying a change fee. Changing your flight on or the mobile app will automatically waive any fees, if applicable. Travel waivers currently in effect can be found here.

Special requests

  • You can add these to your reservation by selecting “Edit traveler information” from the reservation.

  • You can place a request by selecting “Special requests and accommodations” from the reservation.

  • When viewing your reservation you can select “Add pet” under Special Requests and Accommodations. For additional information, please visit the Traveling with Animals page.

General information

  • Your confirmation number is a 6-digit alpha-numeric code which can be found on your trip confirmation or ticket receipt.

  • For an upcoming trip or past trip, view the reservation and select “View receipt,” or request an email receipt from this page. You can also request receipts for inflight purchases on this page. If your past trip is no longer displayed, please request a past receipt.

  • You can place a special needs request by selecting “Special requests and accommodations” from the Trip Details page. See the customers with disabilities page for details. Please note some special needs assistance is not available on all flights due to aircraft type or other considerations.

  • Certain countries, including the United States, have travel document requirements for departure. Please note these requirements may be different from travel document requirements for entry into the destination country and for transit through a country.
