I called Fubon CS, the staff reply makes me very confused.
He said my max points gain is 3X of my limit = 210,000.
so he advises me to spend $50,000 can get the max points.
I call BOC CS to verify.
Now BOC Visa Infinite is $2.5/ Asia Mile if I can spend $15,000 or over.
According to fubon Staff reply.
for examples, I will $45,000 in Japan.
the first $20,000 can earn 80,000
the rest $25,000 can earn 100,000
total can earn 180,000 points = 15,000 asia miles.
in other words $45,000 = 15,000 miles = $3 for 1 Asia Mile.
Hence BOC Visa Infinite is better than fubon.
Am I right?
