Airbus was very good for it's day, but that was a long time ago...
The Wilco/FeelThere packages are the best Airbus currently available for FS9. Wilco/FeelThere get lots of negative comments on the various FS
forums, and much of it is rightly deserved. Their Airbus packages aren't in the same league as PMDG or Level D, but they are much more sophisticated than the likes of CLS. Also bear in mind they don't feature the A340-200 or -500. The visual models aren't great either and there aren't so many repaints available. If you can live with losing the VC
and are savvy with merging aircraft you can replace the FeelThere models with much better ones either commercial or freeware. For the A318/19/20/21 I use the old IFDG models that are still great and have an enormous number of repaints available, and for the A330/40 I use the fantastic models from Overland (commercial addon) with the equally fantastic repaints by Tom Collins, available on Avsim.
As I said the Wilco/FeelThere packages are the best available right now, but come with the following caveat emptor - the customer support is shameful, the visual models aren't the best available and have limited repaints, and the documentation is pretty poor compared to other developers.
AirlinerXP - announced last year and has since been delayed indefinitely. The reason being one of the key developers has apparently left the project. The other developers are being very tight lipped about the whole situation which has no doubt caused them great embarassment after the fanfare and hype it was announced with last year.
There is another Airbus in development from a Russian group, I can't remember the name now, but like AirlinerXP they have been very quiet for a very long time now which makes you wonder as to the status of the project.
