Thanks in advance for the help!!

We're moving to Taiwan for the foreseeable future, so obviously the addition of EVA makes this an interesting choice.

Two use cases:
- I will travel to SFO at least three times a year, and likely somewhere else far one other time a year (strongly prefer direct, which means EVA)
- The entire family will travel to Chicago once a year. We prefer Asiana (this is why we are currently members), and like to avoid US airlines.
- We will have minimal flights within the US
- My wife and I will travel around Asia every few months

We're long-time members of Asiana, and each of us has around 40~50k. We're all Gold Members currently.

Finally, I currently use the SPG Amex, but am open to changing, especially if there is a card that doesn't charge international fees. Unfortunately the Asiana AMEX has a 1% currency conversion fee.

Thanks again!
