They have Avanti Is and IIs - the IIs are ProLine 21 equipped (very nice glass). Newhires go into one or the other initially and probably IIs over the long term as they get more delivered. With the exception of the recent FO flying rule change (see above), it seems like a solid company with many great domicile choices and interesting/varied flying. You will see a lot more of the country flying with Avantair (fly into a lot of smaller airfields in remote places in addition to the normal Class B airports) than you would with any regional. Seems like their pay is pretty competitive too.

Good luck.
