AN EXISTING TICKET
United’s My Trips is the recorded route for finding a reservation and reviewing change options. Refund requests use their own online page, and the original seller matters when a ticket was bought elsewhere.
Start with United Airlines’s official booking or help resource below to find the route for your ticket. Look at the replacement flight and any fare difference before accepting a change.
A cancellation may lead to a credit, a refund or no remaining value, depending on the ticket and circumstances. Read the options shown by the airline or ticket seller before confirming.
Keep the cancellation confirmation. A refund request may be a separate step, and this directory cannot approve or process it.
Official change and cancellation guidanceOfficial refund informationAn airline-initiated schedule change is different from choosing to cancel your own trip. Check the message from United Airlines, retrieve your reservation and review the alternatives it offers before making changes.
This page is a contact guide, not a live cancellation feed. Confirm the status of a particular flight on the airline’s website or in its app.
