And, PVG-YYZ is not especially expensive.
She goes to school in Toronto, do you think it's more likely that she took a year off to fly YYZ-YVR-PVG-YYZ, or she took two trips, one to YVR and one to PVG. I'm not sure why you keep arguing that PVG-YYZ is not expensive, and it doesn't really matter. Do you think Mrs. Qian doesn't know to search airfare on aircanada.com, expedia, or ctrip and blindly pay whatever CaptainCooll offers or is it more likely that she searched prices first and decide to go with CaptainCooll's price is his price is so much cheaper than other places.
