Thanks for reply my fellow *A friends.
My intention in creating this post is to tried to compare 20+ Frequent flier program on Star Alliance AIrlines in which other could also used for reference.
My scenario is that I live in the US and my flight is 30% Transpac and 60% Domestic. The UA/CO program is treating me fine, but all I want is just a quick way to gain Gold Card so that I can sneak into the lounges everytime I fly.
Second scenario for you guys to figure out for fun
My AUnts lived in Bkk and is a Thai ROP. She travel to Europe roundtrip twice per year to Oceania twice per year and once per year to HKG and NRT. She just want a Gold Card.
What do you guys think
