Extra Seating

As a friendly reminder, guests who are unable to safely and comfortably fit in a single seat are required to purchase an additional seat.

Extra seating is required if any of the following criteria are not met:

  • The passenger must be able to properly attach, buckle, and wear the seatbelt. One extension is available if necessary. The average length of the seatbelt extension is approximately 22 inches.

  • The passenger must be able to remain seated with the seat armrest(s) down for the entirety of the flight.

  • The passenger must not significantly encroach upon the adjacent seating space. See our seat dimensions.

Extra Seating

Regardless of the actual additional length the extension provides, if a passenger does not meet criteria listed above when using the extension provided on-board, it will be necessary to purchase an additional seat, where available.

Island Air reserves the right to deny boarding of a customer who declines to purchase a ticket for an additional seat for each leg of his or her itinerary when required.

The second seat may be purchased for the same fare as the original seat, provided it is purchased at the same time. We strongly recommend advance purchase to secure your travel plans as the fare to purchase a second seat may be higher on the day of departure. Under these circumstances, no refunds will be made should your flight have available seats upon departure.

Additional Procedures

The additional seat must be available without unseating another customer. If an additional seat is not available on the same flight, the passenger is required to rebook on the next Island Air flight with seats available for accommodation. Island Air will waive penalties or fees that may otherwise apply to this change.

If the customer is away from his domicile and must rebook for a flight the following day, amenities, meals, and hotel accommodation are at the customer’s expense.

Baggage Allowance

Passengers who are required to purchase an extra seat is not allowed double the baggage allowance.They are allowed the same as every other passenger. The number of carry-on items permitted is determined by the individual passenger allowances set by the Transportation Security Administration (TSA), rather than Island Air policy. Consequently, the carry-on allowance is not doubled. Visit our Baggage page to find out more about allowances.
