Second, I'm looking for a program where my miles can be earned through credit card purchases, as I don't fly enough to accumulate miles through travel.

Third, though I want to use my miles for international upgrades, I feel like it would be better to join a *A US carrier (because I fly domestically more than internationally, and they have more mileage based credit cards available) such as United/Continental/Delta.

My question is, if I earn 100k miles on Delta's ffp, can I redeem those for an upgrade on Singapore Airlines, or Asiana? I understand that this only works for certain booking classes, but I'm having trouble finding a simple, concise answer to this (maybe there isn't one).

Thanks for your help, and I'm sorry if I rambled.
