If you purchase tickets in the first and main cabin class and you have to cancel your flight for whatever reason, you won't be charged a flight cancellation fee according to Alaska Airlines' cancellation policy. However, there is no need to pay additional costs, if you meet the 24-hour cancellation requirements. You receive travel credit points from the airline, which you can apply to your subsequent reservations.
