Yes, they're global, but generally not as lucrative. Korean and Singapore both have good programs if your focus is redeeming for their flights rather than partners. British Airways has a program with some great redemptions but on the whole, not as much. There's value to be had in the non-US programs but it requires more work. I use Singapore and Korean's programs heavily for long-haul first class redemptions to/from Asia. I can transfer points earned at various banks in the US to those two airlines. And then of course there's frequent flyer status which is often much better outside the US than domestically.
