Signature Flight Support and Avfuel further solidified their business relationship with an agreement last month. Avfuel, the largest independent fuel supplier, already had contracts to provide fuel for many of Signature’s 30 locations, but the new arrangement–identified by both parties as “a major fuel-supply agreement”–formalizes the relationship.

As part of the new pact, all domestic Signature locations will now offer Avtrip incentive points. Under the Avfuel program, pilots earn points for each gallon of fuel they purchase. The points are credited toward U.S. savings bonds or international equivalents. More than 10,000 pilots receive points every year, according to Avfuel. There is no cost for pilots to participate.
