Beijing <72hrs, then Cathay Pacific to HKG/DPS

Hello,
Do you think I can enjoy the 72hrs free transit visa if I am flying from Dallas to Beijing, 72hrs later I would have an award confirmed ticket from Beijing to Bali connecting this route via Hong Kong (Beijing/hong kong/Bali on the same cathay pacific reservation? Or should I use singapore airlines and leave beijing to singapore/Bali? thanks
