China Airlines (CAL) and Hainan Airlines will cooperate on a joint mileage program beginning Sep. 1, as frequent-flyer members on both airlines will be able to accumulate and redeem the miles interchangeably.

Beginning Sep. 1, members of China Airlines Dynasty Frequent Flyer Program can accumulate air miles while taking regular flights on Hainan Airlines, including cross-strait flights.
