Planning to spend a month in Thailand.
Flying out of YOW (ottawa) preferrably, but would consider YUL or YYZ as well.

I have enough points for business or economy.

Was about to book an economy flight Dec 26 - Jan 27, it was through EVA and the taxes/fees were quite low <$150...however, it appears I was too slow and the outbound flight is no longer available...

I found some options with United/Singapore that result in taxes of approx $350-$400...Is this pretty much the best I can do?

Not against making some stopovers along the way if it helps...

Was hoping someone could perhaps point me in the right direction .

Thanks!!
