The $499 fare is ow from yyz>bkk in Tango Plus(L). This is a pretty good deal considering that there is also a double miles promotion for the segments between yyz & nrt. I booked this fare for an all price of $1297 and considering my superelite bonus I will collect 44,000 aeroplan miles for this trip. Upgrades between yyz & nrt look like a sure thing as well.
