Manage reservations

Changing your flight

  • If your trip is coming up and you’re more than a day away from departure, you may be able to change your reservation with no change fees. You can go to or use our mobile app by selecting “Change flight” to change eligible reservations. You can adjust your travel plans without any change fees — including for award tickets — for flights within the U.S., or for international travel originating in the U.S. This applies to most United Economy and all premium cabin tickets. You’ll just pay the fare difference if your new flight is more expensive. If your ticket is not eligible to be changed, you will receive a message when you select “Change flight.” Visit our Flight Changes page to learn more about all of your options.

  • Basic Economy tickets aren’t eligible to be changed. You’ll find more information at Basic Economy FAQs.

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

  • You can switch to an earlier or later flight within 24 hours for a reduced fee if you are holding an eligible ticket depending on availability. Basic Economy tickets are not eligible for flight changes. MileagePlus Premier® Silver, Premier Gold, Premier Platinum and Premier 1K® members may request a same-day change at no charge. For all other customers, a difference in fare may apply even if the same original ticketed fare class is available. You’ll find more information on our Flight Changes page.

  • You can select the applicable traveler during the first step in the change path and continue to change flights just for that traveler.

Canceling your flight

  • If your plans change and you prefer not to change your itinerary immediately, you may cancel your flights and retain the value of the unused portion of the ticket as a future flight credit. Visit our Travel Credits page to learn more about them.

  • 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. That 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 gave us your contact information during check-in, you'll receive an email or text message regarding your updated itinerary. You’ll find more information on 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. You’ll find more information on the Schedule changes page.

  • When severe weather or other major events may affect 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 by choosing “Edit traveler information” from your reservation.

  • You can make a request by choosing “Special requests and accommodations” from your reservation.

  • When viewing your reservation, you can choose “Add pet” under “Special requests and accommodations.” Our Traveling with Animals page has more information for you.

General information

  • You’ll find your confirmation number — a 6-digit alphanumeric code — on your trip confirmation or ticket receipt.

  • For an upcoming 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 choosing “Special requests and accommodations” from the “Trip details” page. See the customers with disabilities page for details. Keep in mind that some special needs assistance is not available on all flights because of aircraft type or other considerations.

  • Certain countries, including the U.S., have travel document requirements for departure. These requirements may be different from travel document requirements for entry into the destination country and for transit through a country. You’ll find more information on the International Travel Document Requirements page.

    Entry requirements into destination countries and for transit through a country are provided by the International Air Transport Association (IATA) on the Passport, Visa and Health Requirements page as a courtesy and must be confirmed before travel.
