I was doing some research for an upcoming trip to the US from Sydney and noticed that via Vancouver, AC offer some quite attractively priced business class fares to my final destination, Chicago. I am guessing that the reason they are more reasonably priced is that the Vancouver to Chicago leg is via their regional carrier, has anyone had experience of flying a leg like that in business class into the US? My other question was that would I be considered transit there, with my bag going straight through to Chicago? If anyone had experience of the Sydney/Vancouver leg, I'd love to here that too.
