I apologize as i'm sure this has been asked numerous times. I was just wondering if for international flights such as CX's hkg-yvr-jfk and QF's syd-lax-jfk:
1) If no stopover is made in yvr or lax portion of the trip, does this still count as the one transcontinental sector permitted
2) If I originate in North America, i am only permitted to flight segments. Does the yvr-jfk or lax-jfk count as one of those flight segments (again assuming that no stopover is made in lax or yvr)

Thanks a lot, i appreciate any input
