Found the following on the Qantas website - located at http://www.qantas.com.au/flights/flying/in_bus.html -

"As an international Business Class customer you are invited to access any Business Class lounge operated by a oneworld airline before your flight. You can enjoy the comforts of an Aer Lingus, American Airlines, British Airways, Cathay Pacific, Finnair, Iberia, LanChile or Qantas Business Class lounge. The choice is yours."

My reading of this is that if I am flying out of SIN on a QF J flight, I am entitled to access the CX lounge, regardless of my OneWorld status, et al.

I cannot see this as being correct - anyone else?
