If you get the 330 you will be here as an FO till the fleet dies in 3-4 years
330/340 is slated to be gone end of 2016 with possibly one 340 still flying up to Jan 2017. Even of the plan doesn't go as advertised they won't last more than 2 more years. This means if you do get offered a 330 course you will find yourself on something else within a short space of time, probably 380.
