The airline has pegged entry to its opulent Al Mourjan business class lounge (below) at 450 Qatari Riyals, or A$165.
The sprawling Al Mourjan lounge is the size of 10 Olympic swimming pools and spread across two storeys, which are connected by a grand spiral staircase astride an eye-catching infinity pool water feature.
However, paid entry is limited to passengers on Qatar Airways flights booked by the airline – travellers on codeshare flights and Oneworld partners such as British Airways need not apply. (Tickets booked on frequent flyer points also don't make the cut.)

A flash of cash will also open the door at the airline's designated lounges for Oneworld frequent flyers travelling in economy.
The 'First Class' lounge for Oneworld Emerald members – including Qantas Platinum and BA Executive Club Gold – lists at QAR300 (A$110), with the 'Business Class' lounge for Oneworld Sapphire members (including Qantas Gold and BA Executive Club Silver) at QAR250 (A$92).
However, unlike Emirates and Etihad, entry to Qatar's Al Safwa first class lounge remains restricted to actual first class flyers.
