Best Way to fly to Yangon, Myanmar? ( Nov - December 25 days)?

It depends on where you are flying from. I tend to favor the Asian airlines but I also try to go with the airline that is in the same alliance as the U.S. airlines I have a frequent flier account with. I suggest you look not only at price but also connection time. You don't want a really tight connection but you also don't want a 7 hour layover somewhere either. Unfortunately Myanmar does not have a lot of choices for airlines when compared to say Tokyo. I would check out http://www.orbitz.com/ to find out what suggestions and prices they come up with.

I have been researching the same thing. It seems Korean Air as the best rates.
