My dad, who flies PEK at least once a month, has no negative comment against them.
Except he mentioned that he need to "fight" with others to get a seat on an "earlier" flight in case of the regularly happened IRROPS.
Given CX has almost an hourly departure from PEK, wonder why they dont have their own team. Another thing is the poor quality of the lounge, even worse than the plaza premium lounge in HKG.
