Haslam began his career at Pilot Corporation in 1976. In 1980, Haslam was named vice President of sales, development and operations. At that time, Pilot operated 100 convenience stores with annual fuel sales of about 125 million gallons. Pilot opened its first travel center in 1981, and by 1996 – the same year Haslam was named President and chief executive officer – the company operated 96 travel centers and 50 convenience stores and its total gallon sales had reached 1.2 billion. Pilot Corporation attained yet another milestone in 2001 when it joined with Marathon Ashland Petroleum LLC to form Pilot Travel Centers LLC.
