Global fuel supplier and logistics company World Fuel Services last month completed its deal to purchase Tampa, Fla.-based general aviation fuel distributor The Hiller Group. Hiller supplies fuel to more than 600 FBOs and corporate flight departments nationwide and has an annual volume of more than 120 million gallons. "The addition of Hiller will further expand our presence in both the branded and unbranded general aviation fuel distribution businesses," said World Fuel president and CEO Michael Kasbar.
