I think you were a bit out of line in your response. Just because someone doesn't know an IATA airline code does not necessarily mean they don't belong here. There are hundreds of such codes around the planet. I've been airline piloting for over 25 years and have over 14000+ heavy jet command time, including a fair amount of international flying and I can hardly keep up with the codes in my own country. Get anyone out of his region, and making errors in the codes is quite understandable.
I would never tell you that you didn't belong on the PPruNe forums if you didn't know that J9 is Air Tran Airways.
Nor would I even tell you the you didn't belong here because you said GA is general aviation, when, in fact, it is Garuda Indonesia Airlines.
