So I flew CX PE SYD-HKG and back in the last few days. Both flights are day flights (CX162 and CX139). I redeemed via Asia Miles for 30K each way.
Seat (both ways):
The seat width is not as good as it should as PE. Happy with the recline though, much more than Y. On HKG-SYD leg (CX139) I had the bulkhead row so it is a much better experience in terms of leg room. It is fine for both daytime flights, as it is good for a nap between meals. I would definitely try to get J though if it is overnight.
IFE (both ways): Whilst they still have a lot of TVs and movies, it is nowhere near as much as before. But would still have more than what QF offers.
CX162 (SYD-HKG):
Lounge: I went to The House AND Qantas International J lounge. I was surprised but QF J lounge is MUCH BETTER than The House, so surprised that I had to check that I did go into the right lounge. The food in the House is very disappointing. Not sausage and bacon, but have congee. QF J lounge have pretty standard breakfast offering including sausage and bacon, as well as wider range of drinks. It is operated by Sofitel, and I enjoyed their barista made Ice Latte. The House only provides machine made coffees. Definitely QF J lounge hands down here.
In flight Food:
Lunch: The ling fish with rice is actually OK. I find Gweilo beer funny, but not the best beer around.
Refreshment: The Shepherd's Pie is soggy and taste no good because of it. Betsy beer is not as good as Gweilo beer either.
CX139 (HKG-SYD):
Lounge: I went to The Pier (Business) for the first time, and I have to say that I prefer The Pier to The Wing (I did not go to The Wing this time). The Wing is brighter, but The Pier is more "intimate". The breakfast offering at The Pier (Business) is great for both Chinese and Western versions.
In Flight Food:
I am on the first row in PE, and somehow by the time when it gets to me, the morning Dim Sum had already run out. So I ended up eating western breakfast instead. All I can say is that I am so glad that I had access to the lounge, and had food before hand. As the breakfast tasted bland, and the potato wedges tasted soggy.
The FA though did made up for it by asking me for my preference for the dinner meal. I chose Stir Fried Chicken with rice and it tasted OK.
