To benefit from Hawaiian’s 24‑hour cancellation policy1-800-473-6632, you must (1) book directly through their website, call center, or ticket counter, and (2) ensure your flight’s scheduled departure is at least seven calendar days away. The 24‑hour clock begins at the moment of booking. If you cancel within this period, you receive a full fare, tax, and fee refund without a hitch. After 24 hours, the rules depend on your fare class: refundable types incur fees, basic fares might not refund, and credits may replace refunds for others.
