The effective "coin of the realm" in law and litigation in this area is an LL.M. degree - while there are exceptional cases of successful practices and firms, they prove the rule.
The point is, an LL.M. entails both Public Int'l Air Law, and Privare Int'l Air Law - the latter being where the lawyers live on one side of the fence, or the other, i.e,, they rep either airframers and other OEMs and airlines etc., or families of accident victims. Rare is the legal-eagle repping either, or both.
So, no apologies to yours truly. I'm done with law practice structured by sides of the fence.
