United Airlines Rebooking Policy (2025)

The End of Change Fees on Most United Fares
United Airlines eliminated change fees permanently in 2020 for nearly all tickets originating in the United States, and that policy remains firmly in place through 2025. The old fee structures—often $200 for domestic changes and significantly more for international itineraries—are gone for customers flying on standard Economy, Economy Plus, United First, United Business, and Premium Plus. You can now shift your travel dates, times, or even your destination without paying a single dollar in change penalties. The only cost you may face is the difference in fare between your original ticket and the new flight you select.
This no-change-fee framework covers flights within the 50 U.S. states, between the U.S. and Mexico or the Caribbean, and international journeys that begin in the United States. It applies to both paid tickets and MileagePlus award bookings under the same geographic rules. The policy is not a temporary promotion; it is a permanent part of United’s customer commitment, which means you can rebook with confidence even months before your travel date.
Below, we break down exactly how the policy works, which ticket types are included, and how to handle fare differences and travel credits so you can adjust your itinerary on your own terms.
Which Tickets Qualify for Fee‑Free Changes?
The most important distinction is the fare class you originally purchased. Traditional Economy, Economy Plus, and all premium cabins (First, Business, Premium Plus) are fully changeable with no penalty. You can modify your booking as many times as needed between purchase and departure, paying only any upward fare difference. Basic Economy tickets are the notable exception. They remain largely non‑changeable and non‑refundable, though we cover the few windows of flexibility in that category later.
If you booked through a third‑party travel agency or online travel site, the underlying fare rules still apply, but you may need to contact that intermediary to make the change. The fee‑free structure remains in effect for the airline portion of the booking, though some agencies may add their own service fees.
Understanding Fare Differences and Travel Credits
When you rebook a flight that costs more than your original ticket, you pay the incremental amount. United compares the base fare plus any applicable taxes and carrier‑imposed fees at the time of the change. Because airfares fluctuate, it is smart to use the flexible date calendar on united.com to find a lower‑priced alternative day or time. If you hold an existing travel credit, you can apply it toward that fare difference.
If your new flight is cheaper, United does not refund cash to your credit card for a non‑refundable ticket. Instead, the remaining value becomes a travel credit that is linked to the original passenger’s name and MileagePlus account. That credit must generally be used within 12 months of the original ticket’s date of issue—not the date of the change. The credit can cover the base fare of a future booking, while taxes and fees require a separate form of payment.
During widespread disruptions covered by a travel waiver, United often waives fare differences entirely, allowing you to rebook to a more expensive flight within the waiver window at no extra cost.
The 24‑Hour Risk‑Free Cancellation and Change Window
United honors the U.S. Department of Transportation’s mandate and extends a flexible booking window that applies to all ticket types—including Basic Economy. If you purchase a flight at least seven days before departure, you have 24 hours from the moment of booking to cancel or change the reservation without any penalty. The clock starts immediately upon ticketing, so it is not a calendar‑day grace period.
During those 24 hours, you can:
- Cancel for a full refund to your original form of payment, with no questions asked.
- Change to a different flight, date, or destination—paying only any fare difference, with no change fee.
This window is especially useful when you need to lock in a fare while finalizing travel plans. Book at least a week out, set a reminder for an hour before the 24‑hour mark, and then decide whether to keep or adjust the ticket. Bookings made directly on united.com, the mobile app, or by phone qualify automatically. Most online travel agencies also comply, but always confirm their specific policy before booking.
When United Changes Your Plans: Involuntary Rebooking
Schedule Changes and Cancellations Initiated by the Airline
If United cancels your flight or makes a significant schedule change—one that delays your arrival by several hours or forces a connection overnight—the airline is obligated to rebook you on an alternative flight at no extra cost. You can accept the new itinerary it proposes or search for a different United flight on the same day, or sometimes on days immediately before or after your original date. In many cases, you also have the right to request a full refund to your original payment method, even if you held a non‑refundable fare. This refund right arises because the airline failed to provide the transportation you purchased.
When the schedule change is minor—such as a departure time shifting by twenty minutes—you likely will not qualify for a free change. The exact thresholds vary, but a delay of two hours or more for domestic flights generally triggers rebooking and refund rights.
Weather Waivers and Flexible Travel Policies
During severe weather, air traffic control constraints, or other mass disruptions, United typically issues a travel waiver that expands your options. Check the Travel Alerts page for the latest active waivers. When a waiver is in effect for your travel region, you can rebook without paying a fare difference, as long as your new travel dates fall within the designated window. Even Basic Economy tickets often become changeable during a waiver, letting you preserve the value of a normally restrictive fare.
Acting through self‑service channels under a waiver is usually the fastest way to rebook. The United website and app automatically apply the waiver rules, presenting you with no‑cost alternatives.
How to Rebook Your United Flight
Using United.com
The quickest path to a new itinerary is the “Change flight” feature inside My Trips on united.com. After logging in, locate your booking and select the change option. You will see a calendar of departure dates with the associated fare differences or credits clearly displayed. The site lets you pay any additional amount with a credit card, a travel credit, or a mix of both. Once confirmed, your electronic ticket is reissued within minutes. Because the tool is available around the clock, it can help you avoid phone hold times when disruptions spike.
Through the United Mobile App
The United app mirrors the website’s functionality in a mobile‑optimized format. Open the app, tap My Trips, choose your reservation, and hit Change Flight. The app also supports same‑day changes and will send push notifications with rebooking options if your original flight is disrupted while you are already at the airport. Many travelers prefer the app for its one‑handed navigation and real‑time gate and delay updates.
Via Phone or at the Airport
When you need an agent’s assistance—for itineraries with multiple passengers on separate reservations, unusual routing requests, or the application of older travel credits—United’s reservations team can help. The phone number is on your booking confirmation. To shorten the wait, call during off‑peak hours (early morning or late night U.S. time zones) and have your confirmation code and traveler surnames ready. Airport kiosks and customer service counters can also process changes, though complex reissues may still require a phone referral. United’s callback feature, offered during high‑volume events, lets you hold your place in line without staying on the phone.
Special Situations in Rebooking
Basic Economy – The Non‑Changeable Fare
Outside of the 24‑hour risk‑free window and active travel waivers, Basic Economy tickets remain strictly non‑changeable and non‑refundable. If you need to alter your travel after that window closes, you will lose the ticket’s entire value and must purchase a new flight. Some co‑branded United credit cards offer a limited ability to modify Basic Economy bookings, so cardholders should review their benefits guide. If there is any chance your plans might shift, opting for a standard Economy fare—even if it costs a bit more—can save you from forfeiting the ticket altogether.
Same‑Day Changes and Standby
United allows any traveler to request a same‑day change up to 24 hours before departure. For non‑elite passengers, this usually incurs a flat fee (typically around $75, varying by route) plus any fare difference. MileagePlus Premier members receive much greater flexibility: Silver, Gold, Platinum, 1K, and Global Services travelers can confirm a seat on an earlier or later flight the same day without paying a change fee, often without a fare difference provided the same booking class is available. Standby is also free for Premier members willing to wait for an open seat. Non‑members generally cannot stand by for free unless they hold a flexible fare type. Check the Same‑day change link inside your reservation to see exactly what is available for your flight.
Award Tickets and MileagePlus
Since 2020, award tickets booked through United MileagePlus have been largely free of change and redeposit fees when travel originates in the U.S. You can modify dates, times, or even the routing, paying only the difference in miles if the new award costs more, or having miles returned to your account if it costs less. For international award travel not originating in the U.S., a small redeposit fee may apply, though this fee is frequently waived for Premier Platinum and 1K members. Canceling an award ticket and having miles redeposited is also penalty‑free on U.S.‑origin tickets, making award travel remarkably adaptable.
International Flights Not Originating in the U.S.
While the permanent no‑change‑fee policy centers on flights that start in the United States, international itineraries beginning outside the U.S. may still carry change fees or have more restrictive rules. For example, a ticket issued in another country and starting in Europe or Asia might be governed by that region’s fare conditions. If you are booking such a journey, review the fare rules at purchase and consider a travel insurance policy that covers change fees should your plans shift later.
Multi‑City and Open‑Jaw Itineraries
Rebooking a multi‑city trip with several segments requires careful attention. Each flight segment is part of a single ticket contract, so you generally need to change the entire itinerary or adjust individual legs as the fare rules permit. Fare differences are calculated across the whole journey, which can mean a larger increase if one leg has become significantly more expensive. United’s online change tool can handle many multi‑city revisions, but for complicated re‑routings, contacting an agent may be the safest route to avoid breaking the ticket and losing value.
Refundable vs. Non‑Refundable: Strategic Choices
Refundable tickets give you the greatest flexibility: you can cancel for a full cash refund at any time before departure, and you never need to worry about travel credits or expiration clocks. They are more expensive upfront but can be a smart investment for business travelers or anyone whose plans are genuinely uncertain. Non‑refundable tickets, while cheaper, restrict refunds to the original form of payment except during the 24‑hour window or when United cancels your flight. For most leisure travelers, the current no‑change‑fee policy on standard Economy fares makes non‑refundable tickets a practical choice; you can adjust as needed and just handle fare differences and credits.
Managing Travel Credits and Refunds
How Travel Credits Work
When you change to a less expensive flight or cancel a non‑refundable ticket outside the 24‑hour window (if permitted under a waiver), United issues a travel credit. This credit lives in your MileagePlus account and can be found under the Travel Credits section. It is typically valid for 12 months from the original ticket’s issue date, so the clock starts ticking at purchase, not at the time of cancellation. The credit covers the base fare of a new ticket, while you pay taxes and fees separately. It is non‑transferable and must be used by the same passenger.
Combining Credits and Split Payments
United’s website allows you to apply a travel credit and then pay the remaining balance with a credit card. If you hold multiple small credits, each can be applied to a single booking, though you may need to call if the system does not automatically combine them. Keeping records of all credit numbers and expiration dates helps you avoid leaving residual value unused. Booking a flight before the credit expires—even if the actual travel occurs after the expiration—is fully permitted and a good way to capture the full value.
Pro Tips for Smart Rebooking
- Give yourself 24‑hour breathing room. Book at least seven days ahead and set a calendar alert for the 23‑hour mark. This lets you lock in a fare while keeping the door open for a no‑penalty cancellation or change.
- Evaluate Basic Economy carefully. The potential savings is rarely worth the risk unless your itinerary is set in stone. When in doubt, spend a little more for standard Economy.
- Expand your airport search. During disruptions, switching to a nearby airport—like Oakland instead of San Francisco, or Fort Lauderdale instead of Miami—can reveal seats that a narrow search misses.
- Leverage the app’s proactive alerts. Push notifications often present rebooking options before a gate agent makes an announcement, giving you a head start on securing a new flight.
- Know your rights. The U.S. Department of Transportation’s Fly Rights guide outlines what airlines must do during cancellations and significant delays. Familiarity with these rules can support your case if you need a refund rather than a credit.
- Pre‑plan during travel waivers. If severe weather is forecast, check the waiver before calling. Self‑service rebooking under the waiver often gives you the best flight options without a fare increase.
- Keep credits organized. Note the expiration date and associated passenger name for every travel credit. Use the MileagePlus dashboard to track them, and book before they lapse.
Frequently Asked Questions
Can I change my United Airlines flight for free?
Yes, for almost all domestic, Mexico, Caribbean, and U.S.‑originating international flights on standard Economy and premium cabin tickets. Basic Economy is the main exception, changeable only during the 24‑hour window or when a travel waiver allows it.
What happens if United cancels my flight?
United will rebook you on an alternative flight at no additional cost. You can also request a full refund to your original payment method, even if you held a non‑refundable ticket. Check the travel waiver page for additional flexibility during widespread disruptions.
Can I rebook my MileagePlus award ticket?
Yes. For U.S.‑origin awards, no change or redeposit fee is charged. You simply pay or receive the mileage difference. International awards not starting in the U.S. may have a small fee, often waived for elite members.
Do I have to pay a fare difference when I change my flight?
Most voluntary changes trigger a fare difference if the new flight costs more. If the new flight is cheaper, the remaining value becomes a travel credit. During an active travel waiver, fare differences are frequently waived.
How long do United travel credits last?
Credits from standard non‑refundable tickets are usually valid for 12 months from the original ticket’s issue date. Always confirm the expiration date in your MileagePlus account. Booking a new itinerary before the credit expires preserves its value.
Is there a fee for same‑day changes?
Non‑Premier members typically pay a flat fee plus any fare difference. Premier Silver and above can confirm a same‑day change without a fee and often without a fare difference if the same fare class is open.
United’s current rebooking policy has removed the steep penalties that once made flight changes a costly hassle. By understanding which tickets carry fee‑free flexibility, how to handle fare differences and travel credits, and where to find help during irregular operations, you can adjust nearly any itinerary with minimal stress. Whether you use the website, the mobile app, or an agent, the tools are designed to keep you moving on your schedule—not on the fee schedule of the past.
