PAK West Airlines, Inc.

PAK West Airlines, Inc., doing business as Sierra West Airlines, is a woman-owned small business providing air charter and air ambulance transportation services as a prime contractor exclusively to the Department of Justice Bureau of Prisons, operating from Oakdale, California. The vendor competes across both set-aside (Woman-Owned Small Business, Total Small Business) and full-and-open purchase orders, with set-asides appearing in roughly half of recent awards.

Sierra West Airlines has operated in the federal market continuously since 2003, with over 25 years of specialized experience in secure inmate transfers and medical air evacuation. The vendor's concrete capability footprint centers on nonscheduled charter passenger air transportation (387 of 418 awards under NAICS 541111) and ambulance services (14 awards under NAICS 621910). Representative recent work includes a $45,885 woman-owned small business set-aside with Federal Correctional Institution Terminal Island for transportation authorization (February 2026), a $50,650 total small business set-aside with Federal Correctional Institution Herlong for multi-facility air charter connecting Reno, Victorville, Springfield, and Terre Haute (February 2026), and a $51,575 woman-owned small business set-aside with FCI Terminal Island for medical airlift (August 2025). Older awards from 2023–2024 include $52,971 for an air charter from Laredo to Laughlin Air Force Base (FCI Herlong, July 2023) and $50,988 for a SOAP flight connecting Herlong, Beaumont, and Lexington (FCI Herlong, May 2024).

Customer concentration is extreme and narrow. Five Bureau of Prisons component facilities account for 30% of all awards by count: FCI La Tuna (34 awards, $569 thousand), FCC Coleman (26 awards, $382 thousand), FCC Sheridan (23 awards, $684 thousand), FCC Tucson (23 awards, $513 thousand), and FCC Allenwood (21 awards, $234 thousand). By potential value, the same five facilities anchor 36% of the combined potential value, with FCC Sheridan leading at $684 thousand, followed by FCC Victorville at $653 thousand. All 418 awards are distributed across 69 named Bureau of Prisons component facilities and subordinate prison medical centers within the Department of Justice; no other federal agency appears in the award record.

The vendor operates under two dominant parent Blanket Purchase Agreements issued by Bureau of Prisons. BPA DJBP0700BPA13007 carries 184 task orders valued at $3.7 million in combined potential value; BPA DJBFAOBPA003 carries 111 task orders valued at $1.1 million. A single Federal Supply Schedule vehicle (GS33F0017Y) appears with one task order. The vendor holds no position on government-wide GWACs or multi-agency IDIQs.

Activity has contracted significantly. The vendor received 13 awards in 2022, declining to 7 annually in 2023, 2024, and 2025, with only 4 awards recorded in 2026 to date. Combined potential value across all 418 awards is $7.8 million; combined obligated dollars total $8.3 million (106% of potential value, indicating invoiced revenue exceeding ceiling estimates). Award size clusters tightly between $17 thousand and $53 thousand per purchase order. The vendor operates exclusively as a prime contractor; the source records zero subcontract positions.

Sierra West Airlines' federal footprint is monolithic: specialized air charter and medical transport for Bureau of Prisons inmate movement and medical care, executed through recurring purchase orders from individual correctional facilities. No diversification into other agencies, other transportation modes, or other customer bases appears in the source record. The vendor's recompete exposure is minimal given that the award portfolio consists of discrete, short-duration purchase orders rather than term contracts or standing IDVs with future renewal dates.
