DIERKS BENTLEY has joined the Mile High Club . . . but not the one you're thinking about.  This is the club of people with enough spare cash to buy their own plane.

Dierks was in Duluth, Minnesota last week picking up his custom designed Cirrus SR22T Xi.  Oh yeah, it's sweet.  The "Xi" edition means you get input on what "specifications" you want.

Dierks also went through a week of training in Duluth before taking the plane home.  He even posed with the grunts who built it.
