Unless you're able to pay the premium to go via Europe, it makes it pretty crappy to go on AC from YYZ to BKK. You either have to spent 6.25 hours in HKG or do a milk run through Vancouver. Seeing the value of spending more time in the air than on the ground I'm going via Vancouver -- I guess it's not all bad.
If you can code share via IAD, it should be possible to code share via ORD on UA. That would be easier from YYZ, I should think. I did that trip once. Nice and easy connections in NRT. Just enough time for a shower, a beer, then back on the plane! That is two layovers, though.
