Pilot Travel Centers LLC, doing business as Pilot Flying J, is a chain of truck stops in the United States and Canada. The company is based in Knoxville, Tennessee where Pilot Corporation, the majority owner, is based. The company is owned by Pilot and FJ Management Inc.. The company operates truck stops under the Pilot Travel Centers and Flying J Travel Plaza brands. Pilot Flying J was founded as Pilot Travel Centers on November 15, 1993 in a joint venture between Pilot Corporation and Marathon Petroleum Company. Immediately all Pilot Truck Stops were converted into Pilot Travel Centers. At its inception, the number of stops was around 60; however, that was to be short-lived. In the next few years, Pilot Travel Centers experienced significant growth. Marathon converted many Speedway truck stops, wholly owned by Marathon, over to the Pilot Travel Center moniker starting in mid-2002. Midway through 2003, another major expansion occurred with the purchase of the Williams Truck Stop chain. The Marathon-Pilot joint venture successfully increased the Pilot Travel Center name recognition throughout the United States, as the number of stops more than quadrupled.
