United Airlines will consider different aspects and circumstances before deciding whether to grant a partial refund. It's a great idea to go to the US with a non-refundable ticket as you'll shortly get your money back. Refunds are available for flights that are canceled before takeoff or within 24 hours of purchase. If a flight is canceled, you may always get a refund through United Airlines' online booking page.
