Lets put this one to bed shall we.
The RAFCARS scheme (as was) only enabled military pilots to apply for BA within their last 2 years of service whilst they were gaining their civilian qualifications.
The reason the scheme and subsequent schemes are in place is that in order to access the standard BA recruiting site or, in the past, to get past the 'not qualified' filter, all applicants were required to submit their licence number to proceed.
The military applicants are afforded no further advantage than that. The requirements for the interview, numpty testing and the simulator are exactly the same.
Those throwing 'discrimination' around are scraping the proverbial barrel bottem as it is impossible to claim such when a company is only hunting down the most suitable. If such PC rubbish got that far then the banks and the head hunting companies would be worried.
If you're not yet qualified then apply when you are.
