A good place to go for pretty good AI at the moment that doesn’t seem to be mentiond here yet is http://www.world-of-ai.com/ .They’ve just released their 34th pack today.
Models and flightplans all included in the self installer so it couldn’t be easier to get your airports some life.
Aer Arrann is down the list somewhere and includes the full fleet paints.
As for the Dash models, best bet is still PAI for almost all props.
