Would SQ honour IATA "Fully Endorsable" tickets (if they still exist)?

I think you are quoting in USD?

The cheaper fares are current sales (except maybe AC C and AA D - haven't seen that before).

Yes, all fares were quoted in approximate USD.

There is never a sale on YY fares.

There is never a sale on YY fares.

I realise that. My point being NZ J for example is Business Saver fare, which is only offered in a sale. It isn't the normal fare.
