. Qantas moved 34.5% of international pax in 2002, 28.3% in 2007 and 18.1% in 2012. (BITRE stats)
JQ moved 3.1% of international pax in 2007, and 8.1% in 2012. (BITRE stats)
From that, qantas international is dying quickly, even if you factor in JQ's international flying in/out of Australia.
Don't get sucked in by the Qantas propaganda. Traffic numbers have increased steadily over the past 10 years. Market share may be different but I would suggest that the Qantas group passenger numbers today is higher than 10 years ago. Qantas may not be dying quickly, they may be growing slowly.
