I will be traveling to PVG on September 16th, and have the following flight itinerary:

Sep 16, 2015, CX368, HKG-PVG, 08:35 - 11:10, a333
Sep 16, 2015, CX367, PVG-HKG, 12:20 - 15:05, a333
Sep 16, 2015, CX542, HKG-HND, 16:25 - 21:35, b744
...

And I wish to ask how should I proceed with the first two flights...

I will of course do online checkin and only have cabin luggage.

But specifically,
1) In the early morning of the Sep 16, when at HKG, can I ask them to print all my boarding passes for me? As the mobile boarding pass won't work at PVG.

2) Upon arriving at PVG, what should I do, so that I have enough time to get off and board the same aircraft. (I am assuming this is the same physical aircraft that I will be on...

3) Let's assume I need to have check-in luggage too, what should I do with them?

Thanks guys...
