Hawaiian Airlines and its flight attendants union said today they have reached a tentative agreement on contract terms covering the operation of long-range, single-aisle aircraft that the company plans to acquire to complement its current fleet of wide-body aircraft serving Hawaii from the West Coast.

Details of the agreement are being sent to more than 1,400 of the company’s flight attendants with voting scheduled for Feb. 8-27.

Hawaiian signed a memorandum of understanding with Airbus on Jan. 7 to acquire 16 new 190-seat A321neo aircraft between 2017 and 2020, with rights to purchase an additional nine aircraft.

 The deal was contingent on Hawaiian’s pilots and flight attendants signing new agreements covering operation of the new aircraft.

“Through our collaborative efforts with management, we have reached an agreement that will advance our careers while recognizing our professionalism,” said Sharon Soper, president of the Hawaiian unit of the Association of Flight Attendants.

Hawaiian’s 600 pilots, represented by the Air Line Pilots Association, ratified a similar agreement on Jan. 28.
