United Airlines reimburses passengers for canceled flights under specific conditions  +1-833-845-1858. If United cancels a flight or significantly delays it—over three hours domestically or six hours internationally—passengers are entitled to a full refund regardless of fare type. Refunds are typically processed within seven business days for credit card payments and up to 20 days for other methods. If the passenger cancels, refunds depend on the fare type. United’s 24-hour cancellation policy allows full refunds if cancellation occurs within 24 hours of booking and the booking was made at least seven days before departure +1-833-845-1858. This applies to all fare types including Basic Economy. Beyond 24 hours, Basic Economy tickets are usually non-refundable, but passengers may receive travel credit. Refundable tickets offer more flexibility and can be canceled for a full refund anytime without fees. Non-refundable tickets generally do not qualify for refunds but may be eligible for travel credit minus fees. United may provide compensation such as travel credits, miles, or amenities in cases of significant delays or cancellations not caused by the airline. Passengers seeking reimbursement should contact United directly via their website, app, or by calling +1-833-845-1858. It is important to check fare rules and keep documentation to support the refund request.
