Just an update, I got back last weekend from HKG trip. My first time there, it was great. Luckily I left the day before the demonstrations began.
I too originally had a few troubles with looking up my trip on CX's website. Finally someone at Cheaptickets gave me the proper CX pnr number and I was able to select my seats and check in online. Somehow I was booked into premium economy and my return leg. It's quite a decent product compared to coach. I'd fly it again no doubt.
Other than that, everything went smoothly.
