You resume sounds pretty average with the exception that you are at JB vice a regional. It is about points. You are probably maxed out on job fairs, recs etc. Find other boxes to check...find something to separate yourself from the non-military pack. The entire applicant pool is doing job fairs and collecting recs. Are you a Chief Pilot, Director of Ops, Director of Safety? Have you tried to become a DPE? If you are a CFI have you asked to be able to use it on the outside to promote aviation with Young Eagles etc? Have you given anything back to the community or volunteered to represent your company or further their brand? Have you been recognized by your company for any specific accomplishments? Other than fly the line...how have you helped JB make money or increase their competitiveness?

I'm not suggesting that you haven't done the above...but it has to make it into the application. UAL wants to feel as though they already know who you are 100% from your application and the Hogan/Interview process is a confirmation check on what they have seen in the application.
