Hello

I'm new here, so I don't know if this question is appropriate in this forum, but I love bkk and travel there often from LAX. I've just discovered frequent flyer mileage, but with all the programs out there and the rules and regulations, it can be very confusing.

I usually fly china air for about $550 RT. I'll need 100,000 before I can get a free ticket from there flyer program which rounds up to 7 round trips flights. Ridiculous.

Since China Air is parners with delta, I looked into their skypass program. It seems like I only need 70,000 to qualify, and only 50,000 to RIO, another place I like to travel.

So my question is, what is the best program to join. I'm looking to travel to bkk mainly with side trips to Rio. Someone suggested star alliance, but tickets to bkk are much higher than the $550 RT I'm use to paying on China Air. I don't care about service or upgrades, I just want to earn free coach.

Any suggestions?

TIA
