Cpt crashs (interesting name by the way to provide input on safety!). Netjets maintenance is bad because they do not leave time to the maintenance base to correctly fix the problems. As a matter of fact, all entries in the techlogs are written in Augsberg (but try Augsburg, works better) where we cannot fly neither in nor out according to Jar!!! or in Chester (may be 1 flight for the whole company in the last 10years apart from maintenance)
Fly your inlaws if you like...I am sure they will appreciate.
however you are right Augsburg maintenance is very good.
