Members of Japan Airlines’ JAL Mileage Bank and Hawaiian Airlines’ HawaiianMiles frequent-flyer programmes will be able to accrue and redeem miles on most flights across both airlines’ networks starting October 1.

The new agreement expands upon the two carriers’ existing loyalty partnership launched in March that currently only covers codeshare flights.

JAL Mileage Bank members will be able to earn and redeem miles across Hawaiian’s neighbour island and international network, while HawaiianMiles members can do the same on Japan Airlines’ domestic Japan and international flights.

The expanded partnership means that members of both programmes will now have the ability to earn and redeem miles across a more than 800 daily flights combined.

Hawaiian currently flies to three destinations in Japan – Tokyo (to both Narita and Haneda Airports), Osaka and Sapporo – as well as other destinations in Asia-Pacific, notably Seoul, Beijing, Sydney, Brisbane and Auckland, among others.

Japan Airlines, meanwhile, flies from Tokyo, Nagoya, Osaka and Sapporo to Honolulu, as well as from Tokyo to Kona.

In related news, Japan Airlines will notably offer first class seating on board its flights between Tokyo Narita and Honolulu from December 28, 2018 until January 5, 2019, during which time it will fly its four-class Boeing 777-300ER aircraft on the route. This aircraft features the airline’s JAL Suite first class product as well as its JAL Sky Suite product in business class.

Elsewhere in Asia-Pacific, Japan Airlines is also set to begin codesharing with Garuda Indonesia on select trans-Pacific, regional and domestic services from October 28.
