Yes, you can cancel United flights and get a refund depending on the fare type and timing. United offers a 24-hour risk-free cancellation policy: if you cancel within 24 hours of booking and the flight is scheduled at least seven days later, you receive a full refund to your original payment method. This applies to all fare types, including Basic Economy.

After 24 hours, refundable tickets can be canceled at any time before departure for a full refund. These include select Economy, Business, and First Class fares labeled as refundable. Non-refundable tickets do not qualify for cash refunds after 24 hours but can be canceled for a travel credit, minus any applicable fees. Travel credits are typically valid for 12 months from the date issued.

Basic Economy tickets are non-refundable and usually not eligible for changes or travel credits unless canceled within the 24-hour window. However, if United cancels your flight or makes a significant schedule change, you are entitled to a full refund, even for Basic Economy.

Award tickets booked with MileagePlus miles can be canceled, and miles redeposited, usually without a fee if canceled in advance. No-shows may incur a redeposit fee.

Refunds are processed within seven business days for credit card payments and up to 20 days for cash or check payments. You can cancel flights and request refunds through United’s website, mobile app, customer service line, or ticket counter.

If your cancellation is due to special circumstances like jury duty, illness, bereavement, or military orders, United may issue a refund if proper documentation is provided.

In summary, you can cancel United flights and receive a refund if you act within 24 hours, hold a refundable ticket, or if United cancels or significantly changes your flight. Non-refundable tickets outside these conditions receive travel credits, not cash refunds.
