Change or cancel your United flight

The first thing that matters is your fare. Basic Economy can't be changed at any price, cancelling and rebooking is your only move. Every other fare has no change fee, but you'll still owe any fare difference, and free 24-hour cancellation only works if you booked direct AND at least 7 days before departure. Answer a couple of quick questions and a live agent can tell you exactly what your ticket allows, then handle it for you.

    First question: is your ticket Basic Economy?

    Yes. Basic Economy

    Basic Economy cannot be changed at all, at any price. Cancelling and rebooking a new ticket is your only option. Inside 24 hours of a direct booking made 7+ days before departure, cancelling gets a full refund. Outside that window, it returns only a partial travel credit.

    No, any other fare

    United charges no change fee on fares above Basic Economy. You'll still owe any fare difference if the new flight costs more, and inside the 24-hour window, you can even change a wholly unused ticket at no fee at all.

    No change fee on non-Basic United fares, fare difference still applies 24-hour free cancellation, but only if you booked direct AND at least 7 days before departure Same-day change available, same airports, within 24 hours of your original flight, United/United Express only Basic Economy CANNOT be changed at any price, cancel and rebook is your only option Cancel Basic Economy outside the 24-hour window and you get partial travel credit, not a full refund The 24-hour rule needs BOTH conditions, a third-party booking or under 7 days out breaks it entirely Same-day change may carry a price difference for non-Premier flyers; free standby is also available

    United's free 24-hour cancellation needs two things to be true, not one.

    Book directly with United, united.com, the app, the counter, or United's own phone reservations. AND depart at least 7 days from today. Miss either condition, a third-party booking or a flight leaving sooner, and the 24-hour window doesn't apply to that ticket at all, on any fare, including Basic Economy. That's a stricter mechanic than most airlines' 24-hour rules, which usually only care about the departure-date cutoff.
    The 24-hour rule, step by step
    Before you book

    Check both boxes: are you booking directly with United, not a travel site or agency? And does your flight depart 7 or more days from today? Either answer "no" and the 24-hour rule won't apply to this purchase at all.

    The moment you book (if both are true)

    You have 24 hours from purchase to cancel for a full refund to your original payment, on any fare, including Basic Economy. Non-Basic fares can even be changed, fee-free, inside this same window.

    After the 24-hour window closes

    Basic Economy locks, no changes at any price, and cancelling now returns only a partial travel credit toward a separate new booking. Every other fare still has no change fee, though a fare difference applies.

    Need to fly the same day, sooner or later?

    Same-day change or standby is available on United/United Express, between the same airports, within 24 hours of your original flight, typically free for Premier elites, a price difference for everyone else.

    How United change & cancellation actually works

    The mechanics behind the fork above, fare by fare.

    No change fee, non-Basic fares:

    United Economy, Economy Plus, Premium Plus, First, Business and Polaris all carry no change fee. You'll still pay any fare difference if the replacement flight costs more than your original ticket. United doesn't publish that difference as a flat number because it moves with your specific route and dates.

    Basic Economy: cancel-and-rebook only:

    United doesn't offer a "change" for Basic Economy at any price, there's nothing to buy. If your plans shift, cancelling and buying a new ticket is the only mechanism that exists for this fare, and the outcome of that cancellation depends entirely on the 24-hour rule below.

    Same-day change or standby, same airports:

    United offers same-day change or standby on United and United Express flights between the same two airports, within 24 hours before or after your original departure. It's typically free for Premier elites, subject to fare-class availability; other flyers may pay a price difference, though free standby is also an option, usually simpler than a full change.

    24-hour free cancellation, two conditions, not one:

    Cancel any United ticket within 24 hours of purchase for a full refund, but only if you booked directly with United (united.com, the app, the counter, or United Reservations by phone) AND your ticket was purchased at least 7 days before departure. Book through a third party, or buy closer to departure than that, and this window simply doesn't exist for that ticket, no matter the fare.

    Cancelling Basic Economy outside the window:

    Once the 24-hour rule no longer applies, cancelling a Basic Economy ticket doesn't return a full refund, it returns a partial travel credit, which has to go toward a new, separately booked ticket rather than being applied automatically. Don't assume a Basic Economy ticket has zero value once changed; call us and we'll check exactly what your specific booking carries.

    These rules are United's own published fare terms, not ours, they vary by route, date, and fare bucket, and United changes them without much notice. We'll confirm your exact ticket's rules and quote our service fee before you're charged anything.

    Basic Economy vs. everything else

    Two very different sets of rules, depending on which side of this line your ticket falls.

    Basic Economy

    Most restricted

    • Cannot be changed at any price, cancel and rebook only
    • 24-hour rule still applies, if booked direct and 7+ days out
    • Cancel outside that window and you get partial credit, not a refund

    United Economy and above

    Flexible

    • No change fee on Economy, Economy Plus, Premium Plus, First, Business, Polaris
    • Fare difference still applies if the new flight costs more
    • Same-day change/standby available too, price difference for non-elites

    Not sure which fare you booked? The fare bucket is usually on your confirmation email or in "My Trips" on united.com, or tell us your confirmation number and we'll look it up.

    Have this ready before you call

    Thirty seconds of prep gets it done on the first call.

    • Confirmation number, the 6-character code on your confirmation
    • Passenger name exactly as it appears on the ticket
    • How and when you booked, direct with United or through a third party, and the exact purchase date, decides whether the 24-hour rule applies at all
    • Fare type if you know it. Basic Economy changes everything about what's possible

    United's Basic Economy penalty, a contrast worth knowing

    The kind of detail you won't find written down on united.com itself.

    Once the 24-hour window closes, cancelling a United Basic Economy ticket doesn't give you a full refund or even the full fare back as a credit, it returns a partial travel credit, and you'll book your next trip as a separate purchase. That's a genuinely stricter outcome than how some other network carriers handle the same situation: Delta, for comparison, issues a full-value eCredit for a fee rather than shrinking the credit itself. Neither approach is "free," but the mechanics are different enough that assuming your United Basic Economy ticket works the way a friend's Delta ticket did can leave you short. If you're weighing whether to change plans on a Basic Economy fare, call us before you cancel, we'll confirm exactly what credit your specific ticket carries and whether waiting inside the 24-hour window is worth it.

    Booked Basic Economy and need to change plans? Don't wait past the first 24 hours to decide, after that, the ticket can't be changed at any price, and cancelling only returns a partial credit. If you're still inside that window, and you booked direct at least 7 days out, cancelling for a full refund and rebooking may be your best move.

    Managing the rest of your trip yourself

    Changing or cancelling is only part of it, most of a booking you can manage online, free.

    With your confirmation number, "My Trips" on united.com or the United app lets you handle most of this yourself at no cost: pick or change seats, add checked bags, update contact details and MileagePlus info, and review your itinerary. Arrange special requests, wheelchair assistance, a pet, an unaccompanied minor, ahead of time rather than at the gate. When a self-service change fails, a payment won't go through, the site won't recognize your booking channel, a fare won't reissue, that's the moment a call saves the trip.

    Frequently asked

    Can I change a Basic Economy ticket on United?+
    No. United's Basic Economy cannot be changed at all, at any price. Your only option is to cancel and rebook a separate ticket. Cancel within 24 hours of a direct booking made at least 7 days before departure and you get a full refund. Outside that window, cancelling Basic Economy returns a partial travel credit, not a full refund, and you'll need to book your next trip separately.
    Does United charge a change fee?+
    Not on fares above Basic Economy. United Economy, Economy Plus, Premium Plus, First, Business and Polaris all have no change fee. You'll still owe any fare difference if the new flight costs more. Basic Economy isn't eligible for a change at any price; cancel-and-rebook is the only path there.
    I booked this morning. Can I still cancel for free?+
    Only if two things are both true: you booked directly with United, united.com, the United app, the airport counter, or United Reservations by phone, not a travel site or agency, and your flight departs at least 7 days from your purchase date. Meet both conditions and you have 24 hours from purchase to cancel for a full refund, on any fare including Basic Economy. Miss either one and this window doesn't apply to that ticket at all.
    Can United same-day change my flight instead of a full change?+
    Yes, between the same two airports and within 24 hours before or after your originally scheduled flight, on United or United Express only. It's typically free for Premier elites, subject to fare-class availability; everyone else may pay a price difference, though free standby is also an option. It's a separate, often quicker process than a full change or cancellation.
    I booked through a travel site, not united.com. Does the 24-hour rule still apply?+
    Maybe not the same way. United's 24-hour rule is built around booking direct, united.com, the United app, the counter, or United's own phone reservations. A booking made through a third-party travel site or agency may not qualify, or may be governed by that seller's own cancellation terms instead. If you're not sure how your ticket was booked, call us and we'll check your confirmation before you assume the window applies.
    If I cancel Basic Economy outside the 24-hour window, what do I actually get back?+
    A partial travel credit, not a full refund. United does not return the entire fare, and the credit has to be used toward a new, separately booked ticket. That's a stricter outcome than some competitors: Delta, for comparison, offers a full-value eCredit for a fee rather than reducing the credit itself. Call us before assuming a changed-plans Basic Economy ticket is worthless, we'll check exactly what credit your specific booking carries.
