Four friends of mine today got the TBNT email. 3 of them work for regionals and they have 1,000-1,400 hours Regionals PIC. Only 1 of those 3 had a special tracking issue/minor setback back in initial Regional FO training. Otherwise, clean records. The 4th guy did a few hundred hours at a regional and then went on to fly heavies for an international cargo carrier where he’s at now, around 1,800 turbine time, no TPIC. Not sure on college degrees.
