The main founder HK Express withdrew from U-FLY Alliance after becoming a wholly owned low-cost subsidiary of Cathay Pacific, a Oneworld member, and the alliance became inactive (the official website is invalid).

The founding members were all part of HNA Group, a Chinese conglomerate, until HK Express was acquired by Cathay Pacific in 2019.
