Pick MileagePlus if…
You're targeting one of these specific redemptions: Excursionist Perk: free segment on round-trip awards or Polaris business class US to Europe at 60-77K saver. MileagePlus is the program built for them.
Pick KrisFlyer if…
You're targeting one of these specific redemptions: Singapore Suites/First (only KrisFlyer can book) or Star Alliance Saver Awards in business class. KrisFlyer is the program built for them.
Can you have both?
Yes — and you probably should. Most serious award travelers maintain status (or at least active accounts) across multiple programs because the best partner award for a given route is rarely the same program twice in a row. Find the saver seat first; then book through whichever program prices it cheapest.
