Many employers prefer aviation sales candidates who have a bachelor's or master's degree in business, marketing, or a related field, but they also consider candidates without a degree who have a successful track record in sales and have some background in aviation, either through piloting a plan or working in the industry. Study the specific products sold by the company for which you wish to work and learn the buying trends of the company's target audience. You should also become familiar with the contract language of aviation deals, laws concerning aviation sales, and other related legislation. Seek aviation sales positions at aircraft carriers, charter airlines, and aircraft part manufacturers.
