You do realise at some stations the matrix of lounges passengers can access could get really complicated?
For example you have to consider, for a QF flight for example, Class of Service access to lounges (which may be just QF, QF and OW, or QF/OW/EK or even a partner one included), then you need to consider QF status pax ranked as Gold, Plat+ then other onewold status members (remember QF lounge entry rules are different at QF lounges for QF status than for corresponding OW status holders) and then partner status pax, such as EK and so on. The matrix would be insane.
And let me get this right, you want an agent to say to passenger X:
"SO ma'am you may use the Qantas lounge for your flight today. But I also see you are a Platinum, so you may also use the Cathay First or Business Lounge, The American Flagship lounge, and oh, you are on a QF flight number, so you may use the Emirate Lounge also"
then the passenger gets even more confused.
