Air Canada option
several times I've booked an Air Canada and star alliance option from YOW when I think starslliance matched something another airline initiated. As I recall the last one was under $3000 Canadian and allowed a stop over in Europe. Once I flew to Cape Town, once to Johannesburg. In both cases I open jawed to Dar. As I recall these deals seem to come up in September. I'm currently monitoring. Too bad several of the posts above that mention good prices don't give a ballpark of what the amount was.
