No. Any passenger that needs to purchase an extra seat will only be assessed one change fee. Please be advised that 2 seats will need to be available on the new flight that passenger wants to confirm.
Due to safety considerations, you must still purchase the extra seat if you are unable to properly attach, buckle and wear the seatbelt, with one extension if necessary, whenever the seatbelt sign is illuminated or as instructed by a crew member; and remain seated with the seat armrest(s) down for the entirety of the flight.
This does not mean that you cannot lift up the armrest; however, it must be demonstrated that the armrest can go down. We have to consider the safety and comfort of the customer requiring an extra seat as well as the family member, particularly in the event of an emergency.
No, Island Air Reward miles are based on the passenger segment flown not the number of required seats purchased per passenger.
The Department of Transportation (DOT) has confirmed that airlines are not required by law to provide additional seating or an upgrade in the event additional space is required for a passenger.
