Yes, in 2026, United Airlines allows you to get your MileagePlus miles back if you cancel an award flight, provided you cancel before the flight's departure. United has eliminated redeposit fees for most members, meaning the miles will typically return to your account instantly after the cancellation is processed. If you booked a "Money + Miles" fare, the mileage portion is also refundable back to the original account if canceled. However, if you are a "no-show" and fail to cancel before the plane takes off, you may forfeit the miles entirely or be required to pay a $125 redeposit fee to recover them. For 2026 travelers, it is a vital step to manage your cancellation via the United app or website to ensure the "automatic redeposit" is triggered. Note that any partner booking fees or phone booking fees ($25) are generally non-refundable, but the core mileage balance is protected as long as you act before the departure window closes.
