Folks -
Whilst there is a theoretical 5 year freeze on changing types, that can be got round sometimes. My brother made it from 737 to 777 after about 3 1/2 years by applying for the slots! If there are not enough applicants with the 5 years behind them then you are in with a chance. The same goes for commands - little brother would be a 737 commander by now if he hadnīt chased 777 - contempories of his are getting shorthaul commands after about 5 years (these are all Cadet Entry Pilots, by the way).
