If you want to do a comparison of Cathay Pacific A321neo vs Philippine airlines A321neo then HKG-MNL does it for you. Currently the A321neo you did on Guangzhou to Hong Kong leaves HKG for MNL as CX907 2hrs after the A350-900/-1000 arrival from JFK CX843 when resumed CX899. Regarding HKG-MNL Filipino Caretakers and off duty Filipino Cathay Pacific Flight Attendants take PR back to MNL due to CX being the more expensive option. Even better the whole CX/UO fleet vs PR jet fleet due to them having almost the same aircraft models
