Thanks for that everyone.
To clarify, I'm currently in HKG and have used one of my stopovers on the way out.
On the return I'd ideally like to use the second stopover in YVR, then "transit" YYZ. I know the normal rule for domestic flights is 4 hrs only, but as I'm flying on an international ticket should I be able to get 24 hrs ?
Shareholder - thanks, alas YYZ-IAD is coach only, so I doubt I can get around it this way.
