They work very well above 3000ft as long as you and the cell site that
sees you are in agreement.

This brings to mind something from WAY back.  When I got out of the Marine
Corps, I flew home to VA.  When we hit pattern elevation, I used my ICOM
2M geer (previously cleared with the Airline) to bring up the auto-patch
and telephone my parents to tell them I was en-route to VA.  My HT was
using a whopping 500mw of power.  Granted, I was probably being heard (on
my TX freq) US wide, but, I happened to know a "control" freq that also
was used as an input freq to the WB4SQC (149.29MHz) repeater in Johnson
City, TN and as such, I wasn't worried about causing problems.
