How to Change the Name on Your MileagePlus Account
Correcting or changing the name on your MileagePlus frequent flyer account is separate from correcting a name on a ticket. To update your MileagePlus profile name, you will need to:
- Log in to your MileagePlus account at united.com.
- Navigate to "Profile" → "Personal Information."
- Submit a name change request with supporting documentation (government-issued ID, marriage certificate, court order, etc.).
- If unable to complete online, call 1-866-284-3014 and a representative will guide you through the process.
How to Change or Correct a Name on a United Airlines Ticket
A name on your airline ticket must match your government-issued identification exactly. Even a small typo can prevent you from boarding. United Airlines has a clearly defined name correction policy that distinguishes between minor corrections and full legal name changes.
Minor Name Corrections
A minor name correction typically involves fixing a typo, transposed letters, or a missing middle name. United Airlines allows minor corrections of up to 3 characters for most fare types. These corrections can usually be made without a fee if caught early.
To request a minor name correction, call United Airlines at 1-866-284-3014 and have your booking confirmation number and the correct spelling of your name (as shown on your ID) ready.
Legal Name Changes
A legal name change — for example, after marriage or divorce — requires documentation such as a marriage certificate or court order. United Airlines will update your ticket name to reflect your legal name, but the corrected name must exactly match the name on your new government-issued ID.
Step-by-Step: How to Correct Your Name on a United Airlines Ticket
- Gather your booking confirmation number and the misspelled name on the ticket.
- Locate your government-issued ID showing the correct name.
- Call United Airlines at 1-866-284-3014 and explain you need a name correction.
- Provide the agent with your booking reference and the correct spelling.
- If a legal name change, submit the required documentation as requested by the agent.
- Confirm the corrected itinerary and check that the new name appears correctly on your updated booking confirmation.
Name Correction for International Flights
For international travel, name accuracy is even more critical because it affects visa and passport verification. If you discover a name error on an international booking, call 1-866-284-3014 immediately. Do not wait until the day of departure. International name corrections may take additional processing time.

United typically delivers delayed bags within 24 hours. If your bag is lost, United will reimburse reasonable expenses and may compensate you for the bag's contents up to applicable limits.
Adding Wheelchair or Special Assistance
United Airlines is committed to accessibility. If you or a travel companion requires wheelchair assistance, a mobility device, or other special services, you can add this during booking on united.com or by calling 1-866-284-3014 at least 48 hours before departure. Wheelchairs and mobility devices are transported free of charge and are not counted as checked baggage. Always notify United in advance so the airport team can be fully prepared for your arrival.
United Airlines Seat Selection & Upgrade Policy
United Airlines offers a wide range of cabin classes and seat types, from Basic Economy to Polaris Business Class on long-haul international routes. Understanding how seat selection and upgrades work can help you maximize comfort — sometimes at little or no cost.
Cabin Classes on United Airlines

How to Request or Purchase an Upgrade

- If upgrading with PlusPoints, ensure you have enough points in your account for the route.
- For waitlisted upgrades, your position is determined by your MileagePlus status tier.
- If you prefer assistance, call 1-866-284-3014 and an agent can review upgrade availability and process the request on your behalf.
Complimentary Upgrades for Premier Members
United Airlines Premier Silver, Gold, Platinum, and 1K members are automatically eligible for complimentary domestic upgrades (space permitting). The upgrade clears based on status level, fare class, and time of request. Premier 1K members clear first, often weeks before departure on high-traffic routes. For upgrades on international routes, PlusPoints are required for all status levels.

Some small corrections may be available through the united.com "Manage Reservations" tool, but complex corrections require phone assistance.
United Airlines eliminated change fees permanently for Standard Economy, Premium Economy, Business Class, and First Class tickets on most routes. This means you can change your flight without paying a change fee — however, if the new flight costs more than the original, you will pay the fare difference. If the new flight is cheaper, you receive a travel credit for the difference. The only exception is Basic Economy tickets, which cannot be changed after the 24-hour risk-free cancellation period.
United Airlines allows passengers to cancel any ticket — including Basic Economy — within 24 hours of purchase for a full refund, provided the departure date is at least 7 days away. This policy aligns with U.S. Department of Transportation regulations. To cancel within the 24-hour window, go to united.com → "Manage Reservations" → "Cancel Flight," or call 1-866-284-3014.
Yes. If United Airlines cancels your flight, you are entitled to a full cash refund — not just a travel credit — regardless of your fare type.

To claim your cash refund, call 1-866-284-3014 and specifically request a refund to your original payment method. Refunds typically process within 7–20 business days.

Always verify current deadlines on your booking confirmation, as they can vary by airport.

To change the name on your United Airlines MileagePlus account (for example, after marriage or legal name change), log in to united.com → "My Account" → "Profile" → "Personal Information" and submit a name change request with supporting documentation (marriage certificate, court order, or updated government ID).
