AFAIK, the 'White Tail' guys who went on to BA didn't have to pay for TR as such, however they did have to increase their bond to match those who'd gone through the FPP, so they were still required to fork out approx £15k after finishing the CTC course. Thanks for the other information!
Regarding George Haywards point - does anyone know which partner airlines taking 'White Tails' pay back the bond in full?
