A year in Jet2 to get on a command course is extreamly optimistic in my opinion. You will need 2 sims before even getting your name in the hat then there will be a good 6months to a year to get on a development week. Then a few other hoops.
By which time you have done your RYR command and got 1000hrs left seat and Jet2 will Hoover you up as a DEC and you will get your base of choice and double your potential Jet2 F/O salary
I know what I would do!
Oh wait I did that!
