Signature Flight Support LLC

Signature Flight Support LLC, headquartered in Houston, Texas, holds a single-award indefinite delivery contract with the Defense Logistics Agency Energy valued at $62.4 million and extending through March 31, 2027, to deliver aviation turbine fuel meeting Joint Aircraft Authorizations specifications to commercial airports across nine states (Alabama, Arizona, Arkansas, Louisiana, Mississippi, New Mexico, Oklahoma, Tennessee, and Texas) in support of military operations worldwide. The vendor operates as a prime contractor exclusively; 100% of its federal award footprint consists of prime contracts with no subcontracting activity. Signature Flight Support competes on full-and-open basis under no set-aside designation.

Signature Flight Support's federal role centers on fixed-price aviation turbine fuel delivery with economic price adjustment provisions, the only concrete service the source documents. The company supplies approximately 192.7 million gallons of aviation turbine fuel to the Department of Defense against periodic delivery orders issued by DLA Energy. Representative delivery orders from April 2026 carry ceiling values ranging from $100 to $35,457.90, all issued under the single master IDV established July 1, 2023. The pricing structure preserves cost certainty for the government while accommodating market-based fuel pricing fluctuations. Place of performance for all work is Houston, Texas.

Customer concentration is extreme and non-diversified. Defense Logistics Agency Energy accounts for 19,336 awards (99.4% of the footprint) with $303 million in combined potential value, representing 83% of the $366.5 million total across all awards. The remaining 1% of awards split between the General Services Administration Public Buildings Service (15 awards, $4.7 million) and other Defense Logistics Agency organizations (9 awards). The vendor serves only three distinct federal agencies total.

Signature Flight Support operates under three parent indefinite delivery vehicles. The primary vehicle—Indefinite Delivery Contract SP060015D0033—carries 11,363 task orders and $56.3 million in combined potential value. The secondary vehicle, SPE60723D0054, carries 6,605 task orders worth $14.8 million. A third vehicle, SP060011D0057, represents 1,363 task orders and $40.8 million in potential value. Two GSA Basic Ordering Agreements (GS07B15291 and GS07B16443) account for 91 task orders and $10.3 million combined.

Activity has grown substantially year over year—809 awards in 2019 climbing to 2,631 in 2024—though the rate moderated to 2,024 awards in 2025 and 674 through mid-April 2026, the latter figure reflecting a partial-year snapshot. Combined dollars obligated across the entire award portfolio total $233.8 million, or 64% of the $366.5 million combined potential value, indicating consistent execution against awarded capacity.

The vendor's footprint is categorized almost entirely within petroleum and fuel supply: 17,970 awards fall under NAICS 424720 (Petroleum and Petroleum Products Merchant Wholesalers) and 1,369 under the same category variant, with 93 awards in nonresidential real-estate leasing (from the GSA work). PSC coding aligns to fuel supply—19,350 awards under Liquid Propellants and Fuels, Petroleum Base; 49 under office-building lease/rental. Signature Flight Support operates as the exclusive provider of military aviation turbine fuel on this DLA Energy vehicle with no documented subcontracting relationships or prime teaming.
