Customers of size seating guidelines of Alaska Airlines has all the information you need, here I have extracted the most critical parts of the aforementioned guidelines:
We require the purchase of an additional seat for any customer who cannot comfortably fit within one seat with the armrests in the down position. The armrest is considered to be the definitive boundary between seats; width between the armrests typically measures 17 inches for coach and 21 inches for First Class. The purchase of an additional seat(s) serves as a notification to Alaska Airlines of a special seating need, and allows us to adequately plan for the number of seats that will be occupied on the aircraft.
After you have completed travel, if all Alaska Airlines flights in each direction departed with an open seat available, you will be eligible for a refund of the second seat.
Refund instructions
You can request a refund by using our online form or contacting Customer Care at 1-800-654-5669. Simply provide the name on the ticket, travel dates, flight information and ticket number.
Seatbelt extensions
The seat width on all Alaska Airlines aircraft (armrest to armrest) is approximately 17 inches and the seatbelt length is approximately 46 inches. Passengers needing extra coverage may ask the flight attendant for a seatbelt extension, which adds 25 inches to the seatbelt length. Only seatbelt extensions provided by the specific aircraft operator may be used onboard.
