Joining my mom's family on their annual trip to Putuoshan, flying into Shanghai the night before and flying to Putuoshan the next day. Anyway on the return, I was thinking instead of spending the weekend in Shanghai (which I've been doing these last few years) I want to just stay in HK instead.

Anyway so I did my booking MNL-HKG-PVG/PVG-HKG/HKG-MNL. Eveything seems okay up until when I'm asked to pick out a flight for PVG-HKG, the choices show only flights that leave PVG until noon. I don't know what time we'll get back to Shanghai from Zhoushan/Putuoshan so I'd rather play it safe and get a much later flight instead.

I'm booking on I class, there are no options to take afternoon flights on the list even if I select C/J. If I book on I can I call the reservations hotline to move me to an afternoon flight?
