Have been trss for just over a year. The deal isn't financially great but it certainly sends you up the ladder leaps and bounds. Whatever people say about TRSS and i presume you mean EZY trss, the training is excellent. Rarely will you hear it criticised. Yes CTC is a slightly odd environment but you pop out well trained and the level of adherence to sops on the line is very impressive. Also everyone i have flown with bar a couple have been great to fly with, good CRM and all that good stuff.
I I don't find it particularly fatiguing as yet, but I use my time off for resting not boozing. (incoming!)
The main drawback to it is that I didnt realise as do many that the CAA require 1500 hours and then an LPC. This means that for me I had 1500 hours after my OPC but will have to wait 6 months for my next LPC to get my licence unfrozen and the subsequent pay rise. The company could bring the LPC forward 3 months without any CAA cost or penalty to them - but they wont, naturally. Bank on 85 hours a month to work out how long it will take.
(LPC is annual IR and type rating Renewal, OPC is 6 monthly competancy check by airline)
With regards the bond - as an example if you have 2000 hours and 1000 jet you could try to get into BA on about £55K At ezy if you are frozen you will be on £37K roughly incl. then £44K incl unfrozen and you will also get back £5K as loan repayment for 5 years. So at BA The bond therefore "disappears" when you move to BA cos you get paid more! (BA = longer time to command etc etc but we are only talking trss here!)
remember that while they are 'sponsoring' your type rating by paying you back £25K over 5 years you are getting paid £25K less - so you do in fact pay for your type rating! The loan is however tax free, but you will fall short by about £50 a month on the repayments to the bank. The cheapest way if you have the luxury is to remortgage the house.
My overall opinion is go do it! great kit, great flying, hard work, financially an okish deal if not a little misleading, but dont expect to do it for ever. Take it for what it is which is giving people the opportunity to get good flying experience at largely their own cost BUT BUT BUT the training is good and you will be better when you left than when you started. Enjoy it while you can, then go else where. Or sit and moan with the rest of em!
