Charliehotel47, Another thing to consider is that both IOTC and AAITC are both demanding courses, basically similar. but each differ in their own ways. Why would you willingly think about doing both, when from the outset you can do only one. If your future aspirations are to be commissioned, do it from the start, rather than taking the very much more difficult route of commissioning from Airman Aircrew. You have already jumped through the hoops, don't make life a lot more difficult by having to jump through much smaller and more difficult hoops later on.
