Everyone's advice about self-education non-withstanding and provided that you are flexible, you have exactly two easy choices for your trip to Asia in J, using AA or UA miles.

AA miles: apply for two AA 50K bonus personal and business cards and one Barclaycad US Air card, then wait until US and AA combine their programs. That would give you 140K AA miles that are currently enough to fly to Asia in J or F. Apply for AA cards at least 8 days apart.

UA miles: apply for 55K Chase United TODAY, then for two Chase cards: Sapphire Preferred and one of the business cards, Ink Bold or Ink Plus for 50K bonus. That will give you enough miles to fly in J to Asia -- on United only. Do not apply for all three at the same time.

If you apply at a Chase branch you can get a 70K Ink card, but AF is not waived. That will be enough to fly to Asia in F (United only).

Make absolutely sure you can meet the required spending, or you won't get the bonus.
