I'm trying to decide whether it's worth getting into MR points or just sticking to UR.

After my current trip ends, I'll most likely be living in Austin, TX for the next few years and flying back and forth to Seattle a few times a year.

International travel is likely to include: Indonesia, Thailand, South America, Greece and maybe Japan or non-UK Europe. (In roughly that order of likeliness).

What's the best I can do with MR for this kind of travel? Are they worth focusing on vs UR?

Thanks!!
