I've had a number of friends that retired from mil and did the sim IP thing. Other than the one's that did it for a few months (less than a year, myself included), exactly 0 of them have gone to the airlines. The ones that stayed either had no desire to move on the the airlines or couldn't get hired due to lack of currency. Times were different then, there was hiring but not crazy hiring like we've seen in the past couple of years. Please listen to Sliceback's advice above. I'd skip the sim and get a seniority number now.
