Metrosmoker- go to the Atsb site. Jq standards may be the highest you've seen but they are not airline standards. Regional perhaps. They took 3 attempts to get Lwmo approval- and that was the check department.
The 330 is better, simply cause they failed most of the incompetents back to the 320, a novel way of addressing a standards issue. Nothing to do with not being Qantas, and a lot to do with once being Impulse.
