United Airlines Economy cancellation policy offers flexibility for passengers who need to modify their travel plans. If you cancel your flight within 24 hours of booking and the flight is at least seven days away, you won’t face any cancellation fees. For non-refundable Economy tickets, cancellation fees may apply, while Basic Economy fares are typically non-changeable and non-refundable. Refundable Economy tickets provide the highest flexibility, allowing changes or cancellations without penalties. Travelers can conveniently manage cancellations and modifications through the United Airlines website or mobile app. Always review your fare rules for a seamless cancellation experience.
