This is the most annoying plane in AM right now. I deployed my Airbuses between big cities and it was fun seeing competition lower their prices way below optimal price. However, in routes where I still use a Caravelle, some airliners use an Airbus. I just realized this plane is so annoying.
This means more Airbus for me! 
One of the nice things about playing in Asia this round has been that the competition, including your airline, has been really kind/light-footed; our numbers are small enough, that we can continue to grow without chewing each other to pieces in the manner that's oft described in this forum.
I bought 2 A300s, put them on somewhat trivial routes, and subsequently watched those routes turn into dust. As such, I have no plans on buying any more 300s. Rather, I'm pushing all 6 of my bases further and further out (in the region) with small planes (in addition to longhual, which is much less time consuming).
You (and anyone else) can throw 300s at me until the cows come home and I'll adjust without the slightest tinge of anger. That having been said, I think you'd be better served with smaller/faster planes (because not everyone is as kind as me and there are still lots of green fields out there).
