Hawaiian Airlines plans to enhance its Airbus A330 aircraft with 180-degree lie-flat seats that will be phased into its premium cabins starting in the second quarter of next year. 

The airline, which has 18 seats in first class, said the seats will fold into 76-inch beds and feature an in-flight entertainment experience using large-format tablets equipped with a telescoping tablet arm that adjusts to optimize viewing angle and comfort. 

CEO Mark Dunkerley said during a global media day at the company’s headquarters this morning that the new addition is a result of the airline’s expansion into international markets that require longer flights. Hawaiian’s longest flight is 10 to 11 hours between Honolulu and Beijing. 

Hawaiian is getting its 22nd A330 delivered this month and will have 23 by the end of 2016. The first newly outfitted aircraft is expected to enter the airline’s long-haul market in the second quarter with the remaining 22 A330 aircraft being outfitted with the lie-flat seats from September 2016 through 2017. 

As part of its cabin redesign, Hawaiian also said it will add 28 additional Extra Comfort seats on each A330 aircraft. The comfort option features 36 inches of seat pitch, priority boarding at the gate, complimentary in-seat entertainment and a personal power outlet. 

In the new configuration, Hawaiian will decrease its total seats available to 278 from the 294 now in existence. The refitted aircraft will have 18 seats in business/first class, 68 in Extra Comfort and 192 in the main cabin. The seat pitch in the main cabin will remain at 31 inches.
