Hawaiian Holdings revealed on July 17, 2012, that it had signed a Letter of Intent to acquire turboprop ATR 42 aircraft with the aim of establishing a subsidiary carrier to serve routes not currently in Hawaiian's neighbor island system. In December 2012 it was announced that Empire Airlines would operate the aircraft on behalf of Hawaiian. A fourth ATR 42 aircraft was acquired in June 2018.
On October 27, 2008, Hawaiian announced that prior to the arrival of its new A330s, it would lease two additional Airbus A330-200 aircraft, beginning in 2011, at the same time extending the leases of two Boeing 767-300ER aircraft to 2011 (to be withdrawn from service coincident with the delivery of the A330s). Two weeks later, the airline announced the lease of an additional A330-200 for delivery in the second quarter of 2010, along with negotiating for delivery of one aircraft from the earlier lease agreement to be moved up to the same quarter. In December 2010, Hawaiian ordered an additional six A330-200 aircraft, bringing the fleet total to 15. Further lease agreements were signed with Air Lease Corporation (one aircraft), and three aircraft each from Hong Kong Aviation Capital, and Jackson Square Aviation, bringing the A330-200 fleet to 22. In July 2015, Hawaiian announced the lease of an A330-200 from Air Lease Corporation. The purchase of another A330-200 was announced in December 2016.
Hawaiian Airlines serves destinations in several Asia-Pacific countries and territories. The airline added its sixth international destination, Incheon International Airport near Seoul, South Korea on January 12, 2011. It also has daily and weekly direct, non-stop international flights from Honolulu to Tahiti, Australia, South Korea, Japan, and New Zealand.
ʻOhana by Hawaiian is a regional subsidiary carrier of Hawaiian Airlines. The service is operated using three ATR 42 turboprop airplanes owned by Hawaiian and operated under contract by Empire Airlines. The new service was slated to begin in summer 2013 initially flying to Molokaʻi and Lānaʻi, however the airline was unable to begin during that period due to Federal Aviation Administration delays in certifying ʻOhana's operation. ʻOhana by Hawaiian is fully integrated into the Hawaiian Airlines network.
