UA is not a good barometer, as SQ long-haul premium cabin is typically not available through Mileage Plus. It's been debated over the years whether this is a UA restriction or an SQ restriction, but it really doesn't matter - the bottom line is that with only occasional exceptions, there are no SQ long-haul business class awards available through UA.
The fact is that SQ makes different award releases to different programs. So just because space shows available through one program does not mean it's bookable through another.
This is one reason why AMEX MR are such a good currency for SQ redemptions - you can immediately transfer to KF or Aeroplan.
