What Is the United Airlines Flight Change Policy in 2026?
United Airlines Flight Change Policy Overview 2026
United Airlines (IATA: UA), a founding member of the Star Alliance and one of the world’s largest carriers, serves more than 340 destinations worldwide. Its primary hubs include Chicago O’Hare (ORD), Houston George Bush (IAH), Newark (EWR), Denver (DEN), Los Angeles (LAX), San Francisco (SFO), and Washington Dulles (IAD). Understanding the United Airlines flight change policy starts with one key fact: the airline eliminated change fees on Economy and above in 2020. That policy remains fully in effect for 2026.
Here’s what the current policy covers. On most fare types, you pay only the fare difference when you switch to a more expensive flight. On the other hand, Basic Economy is the one fare type that does not allow changes on most United Airlines routes. Additionally, United Airlines issues a travel credit when you change to a cheaper flight on an eligible fare. All changes must happen before the original flight departs.
To put it simply, the United flight change policy rewards passengers who book Economy or higher with maximum flexibility. Basic Economy travelers, however, face the strictest restrictions once the 24-hour window passes.
United Airlines 24-Hour Flight Change Rule Explained
Think of the US DOT 24-hour rule like a grace period. United Airlines gives every passenger a full day to change their mind at no cost. This rule applies to all fare types, including Basic Economy. The only requirement: your flight must depart at least 7 days (168 hours) from the time you booked.
Therefore, if you notice a mistake right after booking or find a better flight the same day, act within that 24-hour window. After the 24-hour window closes, fare-specific rules take effect immediately. So if you book a Basic Economy ticket and miss the window, changes are no longer available on most routes. In contrast, Economy and above passengers retain the ability to change even after the window closes, though they pay any fare difference.
Does United Airlines Allow Flight Changes on Basic Economy?
Basic Economy tickets do not allow changes on most United Airlines routes in 2026. However, the US DOT 24-hour rule is the one exception that applies even to Basic Economy. Additionally, if United Airlines cancels your flight or causes a significant delay, you can rebook or receive a refund regardless of fare type. In short, Basic Economy passengers have very limited options once the 24-hour window closes. For that reason, many travelers choose Economy or Economy Plus instead if there is any chance their plans might shift.
United Airlines Flight Change Fee by Fare Type
United Airlines Change Fee Breakdown 2026
Here’s a situation that happens all the time. A traveler from Houston booked a United Airlines Economy flight to New York three months ago. Now her meeting got moved up two days. She needs to change the flight but has no idea what it costs. So here’s exactly what she needs to know about United Airlines flight change fees.
Basic Economy:
- Change fee: Changes not allowed on most routes after the 24-hour booking window
- 24-hour exception: Free change within 24 hours of booking (7-day advance departure required)
- Same-day change: Not available on Basic Economy
Economy (Standard):
- Change fee: $0, no change fee

What Happens to Your Fare Difference on a United Airlines Flight Change
The fare difference rule works in three directions. First, if you change to a more expensive flight, you pay the price difference between the two tickets. Second, if the new flight costs exactly the same, no additional payment is required. Third, and here’s what most travelers miss, if you change to a cheaper flight, United Airlines issues a travel credit for the price difference.
Travel credits are valid for future United Airlines bookings. However, they expire based on the fare rules of your original ticket, and they are non-transferable. In other words, only the original traveler can use the credit. That said, travel credits cover a wide range of United Airlines routes and fare types. Consequently, many travelers find them genuinely useful for future trips.

United Airlines Same-Day Flight Change and Special Situations
Does United Do Same-Day Flight Changes for Free?
United Airlines offers two types of same-day changes on eligible domestic routes. Here’s a tip most people don’t know: the standby option costs nothing, while the confirmed seat option costs $75 for most passengers.
Same-Day Confirmed Change:
- Fee: $75 for most Economy and Economy Plus passengers in 2026
- Free for: MileagePlus Premier Gold, Platinum, and 1K members
- What you get: A confirmed seat on an earlier or later same-day flight
- How to request: At the airport counter, on united.com, or via the Fly United app on the day of travel
Same-Day Standby:
- Fee: Free for all passengers on eligible routes
- What you get: A spot on the standby list for an earlier same-day flight
- Your seat confirms only if a seat opens before the flight departs
- How to request: At the airport counter or via the Fly United app
In contrast to the confirmed option, standby does not guarantee a seat. That said, standby costs nothing and works well if you arrive at the airport early and want to try for an earlier departure.
How to Change Return Flight Only on United Airlines
Here’s what most travelers miss: United Airlines allows you to change only the return segment on a round-trip booking. You do not need to touch the outbound flight at all.
- First, go to united.com and click “My Trips.”
- Next, select your round-trip booking and click “Change Flight.”
- Then, choose only the return flight segment from the list of segments shown.
- After that, select a new return date or time and review the fare difference.
- Finally, pay the fare difference if applicable and receive the updated itinerary by email.
Therefore, you do not need to change your outbound flight to adjust the return date. This is especially useful for travelers flying out of Chicago O’Hare or Newark whose return plans change mid-trip.
United Airlines MileagePlus Award Ticket Flight Change
MileagePlus award tickets follow separate rules from paid tickets. The change fee depends on how far in advance you make the change.
- Changes made 61 or more days before departure carry no change fee on most award types.
- Changes made less than 60 days before departure carry a $125 change fee per person on some award types.
Additionally, the My Trips portal does not always support award ticket changes online. For that reason, contact United Airlines directly by phone to change a MileagePlus award booking. Moreover, if you cancel an award ticket within the free cancellation window, United Airlines redeposits your miles back to your account.
United Airlines International Flight Change and APIS Update
United Airlines charges no change fee on international Economy and above tickets in 2026. However, the APIS update requirement applies to every international flight change. APIS data includes your full legal name, date of birth, gender, passport number, expiration date, and nationality. Update this through united.com or the Fly United app right after completing the change.
Additionally, Star Alliance partner segments on the same booking may require coordination with the operating carrier. For example, a Lufthansa segment on a United booking may need a separate change request through that carrier. United Airlines recommends changing international flights at least 72 hours before departure to allow time for APIS processing.
What If You Miss the Flight Change Deadline on United Airlines?
Honestly, missing your departure without changing the ticket in advance creates a serious problem. Under United Airlines’ no-show policy, the airline cancels all remaining flights on your booking the moment you miss the first segment without a prior change. Therefore, always change your flight before the original departure time, even if it’s just hours before.
On the other hand, if United Airlines cancels your flight or causes a significant delay, you have the right to rebook or request a full refund regardless of your fare type. If a flight change turns into a full cancellation, review the United Airlines Cancellation Policy on Ticket Business Class to understand your refund options.
Money-Saving Tips:
- Book Economy Plus or higher if your plans might change; you avoid the Basic Economy restriction entirely.
- Add your MileagePlus number to every booking to qualify for free same-day confirmed changes as a Premier Gold member or above.
- Change your flight online through united.com or the Fly United app to skip phone hold times.
- Act within 24 hours of booking if you spot an error: the change costs nothing on any United fare type.
