I am no longer with AAI so no axe to grind.
It had it's ups and downs but on a whole I enjoyed my 4 years with them on the 767.
The money was ok for me, Around $115,000 for the year and of course acomm. paid for by the company.
The pay was ontime always, although if you were due some extra payments these my have taken sometime to filter through.
For the last few months I flew on the AAE contract, They pay the industry standard but the add on's are a little lower. and again payment was on time.
Would I work for them again in the future, YES
So I get that will answer your questions, But it does not suit every one.
Why did I leave, for personal family reasons. And a new project came up which looked fun.
