The WestJet cancellation policy allows passengers to cancel their reservation within 24 hours of booking without penalty, as long as the booking was made at least 7 days before the flight. After the 24-hour window, cancellation fees may apply, and passengers may be eligible for a refund or credit depending on the fare type and cancellation time frame. https://www.farecopy.com/cancellation/westjet-airlines-cancellation-policy-and-refund-fees
