Just Stop Paying For It !
TR's and Line Training were designed for employees to be paid for by the company that takes them on. A bonding agreement kept the system fair.
Now STRSS/TRSS and PTF are destroying the profession. The CAA SRG and FAA are looking into this loophole that has exploited hundreds of wannabee pilots. TRs were never there for pleasure seekers or Pay to Fly gullable folk.
Do not pay for a TR (self selection is never a good sign to an interview panel) and be very wary even if you passed interviews with a LoCo and got offered TRSS/STRSS - you are NOT an employee until you pass LST or in some cases have passed Line Check.
