Yes, you can cancel United flights and get a refund, but it depends on the fare type and timing. United Airlines offers a 24-hour risk-free cancellation policy. If you book a flight at least seven days before departure and cancel within 24 hours, you are eligible for a full refund to your original form of payment. This applies to all ticket types, including Basic Economy. After 24 hours, refund eligibility depends on the fare rules. Refundable tickets, such as flexible Economy, Business, or First Class fares, can be canceled at any time for a full refund. Non-refundable tickets, which are more common, do not qualify for a cash refund if canceled after 24 hours. Instead, United issues a flight credit, known as a Future Flight Credit, which can be used toward future travel. Basic Economy tickets are generally non-refundable and non-changeable after the 24-hour window unless there is a schedule change or cancellation by United. If United cancels your flight or makes a significant schedule change, you are entitled to a full refund, even on non-refundable fares. Refund requests can be made online through the United Airlines website by accessing the “My Trips” section or the “Refunds” page. Refunds to credit cards usually take 7 to 10 business days. Refunds to other payment methods may take longer. If you miss your flight without canceling it in advance, you are typically not eligible for a refund or credit. In some special cases, such as medical emergencies, bereavement, or military orders, United may consider refund exceptions, but documentation is required. Award tickets booked with miles may be refunded according to the MileagePlus program rules, often with a cancellation fee. Future Flight Credits are usually valid for 12 months from the original booking date. It is important to review the terms and conditions of your fare class before canceling. To summarize, you can get a refund for a United flight if you cancel within 24 hours of booking, if you purchased a refundable ticket, or if United cancels or significantly changes your flight. Non-refundable tickets do not qualify for cash refunds but may be eligible for travel credits.
