I am flying BKK-HKG-YVR on CX. BKK-HKG flight leaves at 11:30.

I am flying from USM (Koh Samui) to BKK that morning on PG (Bangkok Airways). My understanding is that PG will allow me to check-in my bags all the way through to YVR: see http://www.bangkokair.com/informatio...ECK_IN&lang=en

If I arrive in BKK at 08:50, does this leave me ample time (2h40m) to catch my connecting CX flight to HKG? Will I need to check-in with CX in BKK or can PG issue me all of my boarding passes in USM?
