Nearly 2.4 million seats are scheduled to arrive in the Islands through the end of February, according to the Air Seat Capacity Outlook report released by the Hawaii Tourism Authority late last month. More than 1.5 million of those are expected to come from the U.S. mainland, a decline of 5.1% year over year. Seats from the U.S. West are expected to be off 3.1%, and those from the U.S. East are projected to sink 19.3%. Seats on flights arriving from international destinations, however, are forecast to jump 16% over the same period last year, with those from Japan climbing 2.1% through February and seats from Canada surging 29.4%. HTA officials expect available seats on international flights from Sydney to rise 39.1% year over year and those from Seoul to jump 58.8%. The HTA report is based on information in the Official Airline Guide flight schedules and Sabre databases as of November.
