I'm based in the US and I use a combo of CX/JAL when traveling within Asia. Although I always prefer CX when flying to/from NRT/TPE/HKG, I will have no choice but to use CX and there will be fewer flights to choose from. I will also miss the first class JAL lounge. The real problem for me is being able to use NRT as a connecting point on JAL to other destinations in China such as PEK and PVG.
