Keep in mind that NetJets is a luxury brand that provides world class customer service to high net worth people. Experience working for a premium brand, or with high net worth people, particularly in a service role will be deemed as invaluable experience. In addition to working at an FBO that services private and corporate jets, the hospitality industry comes to mind, such as 4 and 5 star hotels, high end caterers and even aviation companies such as Silverjet. I think the main point is to get relevant real world experience and not just a life of school, even if you go to top schools and get great results.
