For Amadeus: Awards/OneWorld
Note: When searching for premium cabin awards (Premium Economy/Business/First), always check availability segment-by-segment, when using this Method. Otherwise, premium cabin availability may be indicated, when it only exists on some, but not all sub-segments. Alternatively, use the [Awards/BA-OneWorld] Method, which shows Award/Upgrade Availability on a per-segment basis.
So, I'd say either search segment by segment or use BA-OneWorld.
