Question about YVR connection procedure, as my prior flight is from BOS via SFO to YVR (UA, Y), landed at 1 pm and then YVR via HND to SYD (ANA, J), depart at 4:15 pm.
Will 3 hours 15 mins layover enough to transit at YVR (not a US or CA citizen)? Do I need to collect my checked bag at YVR? or maybe the checked luggage can straight forward to the final destination, SYD (Separate tickets)?

Thx!
Kyle
