Available air seats between the Islands and the U.S. West, Hawaii’s largest source market, are expected to climb 5.8% over the next three months, according to the Hawaii Tourism Authority’s (HTA) most recent Air Seat Capacity Outlook. Seats from the U.S. East, meanwhile, will likely jump 7.2% through the end of February. Significant improvement is expected from domestic gateways like San Francisco, up 22%; Seattle, up 14%; and San Diego, up 14.7%. The HTA is forecasting international seats to Hawaii will decline, however, dropping 1.4% year over year through February. Seats on nonstop flights from Japan, Hawaii’s largest foreign source market, are projected to sink 5.7% over the next three months.
