@@@ What credit cards give the best miles? Can they be used to fly home, USA-BKK or BKK-USA?@@@

First of all, sorry for typing in English na kha (using roommate's labtob, no Thai fonts kha).

I'm currently living in Boston area. Never have a credit card that can redeem for any airline tickets before (both domestic and international). I'm wondering if anybody here can recommend me a good credit card that is great to earn miles, no expiration, no fee is possible, etc.

I do interest in credit cards that can earn miles for asian airlines like Cathay, JAL, Korean or SQ.

Thanks in advance for your help na kha.

Happy New Year to all kha.
