Keg,
Just so we can compare apples with apples - what are the QF training requirements for a FO on the 737 to progress to a command on the 737?
Do current FOs on the 737 hold command endorsements on the 737?
You are completely incorrect in your assumption that J* management are happy with the quality of the Alteon training. A manager at J* (who is no longer working there) signed a 10 year (I believe) contract that has locked the company in (perhaps the same guy that purchased A330-200 in a domestic config). I did the Alteon A320 conversion and was not happy with it either.
Having done the QF A330 conversion as well I would only rate it marginally better than the Alteon one.
