This is a very strong program.
Being two round trips Asia/US per year, I can typically make to Gold and not 100% sure on Platinum.

It does give lounge benefits for mid-tier.

My big question. How does the stopover and open jaw rule for the award? especially intra-asia? those would be the key for whether i will switch all my business to *A (CO) in the future. I dont like UA because of starnet blocking.

Thanks.
