United Airlines Economy cancellation policy offers flexibility for travelers who need to make changes. If you cancel within 24 hours of booking, and your flight is at least seven days away, there are no cancellation fees. Non-refundable Economy tickets may incur a cancellation fee, while Basic Economy fares are typically non-changeable and non-refundable. Refundable Economy tickets, however, provide more flexibility, allowing free cancellations and changes. Passengers can manage their cancellations and adjustments quickly through the United Airlines website or mobile app. Always review your specific fare conditions to ensure a smooth cancellation process.
