Customers of size seating guidelines

We strive to best serve our customers' unique needs by providing a safe and comfortable flight for all passengers.

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. Most importantly, it ensures that all customers onboard have access to safe and comfortable seating.

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.

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.

Seat belt extensions are prohibited:

  • in Exit Rows
  • Rows 1 and 6 on Alaska Airlines flights 1-999

Customer of size policy Q&A

If a second seat has not been purchased, you'll be asked to purchase an additional seat before boarding the aircraft. An agent will put you in contact with our reservations department to book and ticket your second seat. There's always the possibility that there will not be enough time to purchase the second seat before your flight departs or your flights may be full and two seats are not available together, so we encourage you to purchase your second seat when you make your initial reservation. If it is determined onboard that you require a second seat, you will need to deplane and rebook two seats on the next available flight.

Many things can occur before a flight departs and a flight that may have open seats one hour before departure may not have any extra seats available at departure time. Purchasing a second seat in advance of your travel date will ensure you receive the same level of service on all of your flights and eliminate any possible travel disruptions. If your flights do depart with empty seats, our second seat refund policy is very simple and the turnaround time for your refund is minimal.

Aircraft type Coach class First Class
737 17 inches wide 21 inches wide
Q400 17 inches wide n/a
CRJ 200 and 700 17 inches wide n/a
E175 18 inches wide 20 inches wide

Please note, the armrests in First Class do not rise. If you're unable to comfortably fit into a First Class seat, you'll need to purchase two seats in the Coach cabin. . Also, the armrests do not rise in row 6 on 737 & E175 aircraft, seat 1A on Q400 aircraft, and row 1 on CRJ 200 & 700 aircraft.

If you are not eligible for a refund of the second seat because your flights departed full, and you are an Alaska Airlines Mileage Plan™ member, you can receive Mileage Plan™ Bonus Miles for the second seat only on flights operated by Alaska Airlines, Horizon Air, PenAir between Anchorage and Dutch Harbor, and SkyWest flight series 3300-3499. The Bonus Miles are equivalent to the mileage you received for each eligible flown segment. You may contact Customer Care at 1-800-654-5669 to request miles once you have completed travel. Please note, these Bonus Miles for the second seat do not count towards Elite Status qualification.

The option to purchase an extra seat is available only to those individuals who require this service based on our seat dimensions. The purchase of an additional seat is required for anyone who cannot comfortably travel with the armrests in the down position. Any customer who purchases a second seat, and who does not meet the criteria described in our second seat policy, will be ineligible for a refund of the second seat.

A seatbelt extension is not a viable substitution if a passenger cannot travel comfortably with the armrests in a down position. However, a seatbelt extension is available to any passenger who requires one. A standard airline seatbelt extends approximately 46 inches, and a seatbelt extension adds approximately 25 inches.

We have a separate policy for pets, service animals, and cabin-seat baggage. Our second seat policy is not intended for those purposes and may not be purchased for such intent.

When purchasing in advance, the additional seat is priced the same as the fare you select. Both seats must be purchased at the same time to receive the identical price. If you choose to purchase a second seat at a later date, we will make every effort to sell the second seat at the same price as the first. However, if we cannot determine your original ticket price due to a group fare, or if you are traveling on a free ticket, we will offer you the lowest available fare at the time of booking for the second seat.

Yes. Any traveler who cannot comfortably fit within one seat with the armrests in the down position is required to purchase a second seat, even when traveling with a family member in a nearby seat. To ensure you are able to travel on the same flight as your family members, remember to purchase your second seat when you purchase your initial flight reservation.

Checked baggage charges and allowances are applied to each seat purchased. The number of carry-on items permitted is determined by the individual customer's allowance. When two seats are purchased for one customer, the customer may bring one carry-on item, plus one personal item.

Every airline has its own policy for purchasing a second seat and we are only able to assist you with booking a second seat on flights operated by Alaska Airlines, Horizon Air, PenAir between Anchorage and Dutch Harbor, and SkyWest flight series 3300-3499. Please contact the other airline directly to learn the specifics of their second seat policy as well as reserving and purchasing a second seat.

You'll only be charged a single change fee to complete your transaction. We strongly recommend changing your reservation as soon as possible so we can guarantee the required additional seat.

If you change your reservation, and the new fare is higher than your original fare, you will be responsible for any difference in fare for both seats, in addition to a single change fee.

If you require extra time to board the aircraft, please feel free to pre-board when the announcement is made.

Yes, however, please know we are unable to guarantee all three seats together. Should this occur, we are unable to guarantee accommodations for the traveler who did not purchase a second seat. To ensure you are both able to travel on the same flight, we strongly recommend purchasing a second seat for each traveler who requires one.

Yes, you may use your companion fare discount code to purchase a second seat. In the event your flight is not full, your Companion Fare Discount Code will be exchanged for later use. Please contact Alaska Airlines reservations at 1-800-252-7522 to complete the transaction.

Title II of the Americans with Disabilities Act (ADA), Section 12141(2), specifically excludes airline travel. Airline travel is instead, covered by the Air Carrier Access Act (ACAA), 49 U.SC. 1374© and regulations implementing the Act issued by the Department of Transportation as 14 CFR Part 382. The ACAA preceded the ADA, and Congress excluded air carriers and other air transportation services from the scope of ADA.

As regulated under 14 CFR 382.87: Seating accommodations (f) "Carriers are not required to furnish more than one seat per ticket or to provide a seat in a class of service other than the one the passenger has purchased."
