Thanks for your information. I would like to know more about this.

I can fly to Toronto, no problem. But my question is : how can we book this cheap fare? Is it on the United website? Do I have to go through a UA agent?

What is the routing from Toronto to SIN? Do we have to go through Seattle or San Francisco? That would get me even more miles I guess. I would have to find a one night hotel stay at the airport in Toronto but that's no big deal.

Are stopovers allowed with such a low fare and what is the minimum required stay in Singapore? I suppose it will be 6 days.
