Thanks for the rapid response Chris. There is one major benefit in flying from NRT, even if it is Jetstar...... Given the new Haneda flights from July 31, I wonder if Qantas will look at a new designated lounge...

Can you enter this lounge as a Qantas Club member booked on a Qantas codeshare flight (using JAL) to Sing? Oh, unfortunately in cattle class. I'm guessing not, however appreciate any comments.
