*Update* The deal is dead.
Basically, if you use travelocity and search for a one-way from RGN in Myanmar to eastern Canada, like YYZ, first class tickets are like $500+. That is incredible for people finding Thai Airways and Swiss First Class.
Here’s the flyertalk thread to see what others have been booking. You may have to use the multi destination tool. And after you book your ticket you’ll need a ticket to Myanmar. Still, this is a good price for a ticket, it’s a good fare for earning miles and would be a real treat!
Good luck!
