I have a question on *A Gold baggage allowance.

I will be flying ZH in F at SZX and the stated allowance is 40Kg with no number of bags restriction.

I am a UA MP 1K as well as a SQ KF Gold, which makes me a *A Gold. I will most likely accrual my miles to SQ as I need the EQM to requalify by April.

What exact is the *A rule? I called ZH and asked and was told I have to check with my *A airline, in this case, it would be SQ. This does not seem right.

I always thought there is a standard *A rule which is either 100% of the weight or 1 more luggage.

Can anyone share some information?

Thanks in advance
