Hawaiian Airlines flight attendants have ratified a tentative agreement reached earlier this month between the company and the Association of Flight Attendants on new contract terms covering the operation of long-range, single-aisle aircraft the company plans to acquire to complement its current fleet of wide-body aircraft serving Hawaii from the U.S. West Coast.

On Jan. 7, Hawaiian announced the signing of a memorandum of understanding with airframe manufacturer Airbus to acquire 16 new A321neo aircraft between 2017 and 2020, with rights to purchase an additional nine aircraft.

Hawaiian’s pilots ratified a similar agreement between the company and the Air Line Pilots Association on Jan. 28.
