I am a AP Elite and am planning an upcoming trip to Asia via AC and SQ on an economy class ticket. Potential connecting stops are PVG or PEK. I will be in transit and not planning to "enter" China (ie. I don't have a Visa), and will have to wait between 3-5 hrs for connecting flights. Questions:
1. Are there Star Alliance lounges in the international transit part of the PVG and PEK airports?
2. What are the operating hours for Star Alliance lounges in PVG and PEK
3. Which of the lounges is more comfortable with amenities like showers?
