Mokulele Airlines has introduced a new $299 monthly pass for September for frequent interisland travelers.
The new pass, which must be purchased by Aug. 31, provides for unlimited travel during September, subject to seat availability.

All flights must be booked by midnight three days before the scheduled departure and there are no refunds for missed flights.
Transfers and name changes for the pass also are not allowed and customers who do not show up for scheduled flights can have their passes suspended. Other restriction may apply.
