21 Air

21 Air, LLC operates as a specialized all-cargo airline headquartered in Greensboro, North Carolina, with executive offices located in Doral, Florida. Founded in 2014, the carrier holds FAA Part 121 certification and focuses exclusively on ACMI charters rather than scheduled passenger service. This business model involves providing aircraft, crew, maintenance, and insurance to logistics partners who require flexible capacity without managing their own fleet operations.

The company serves as a primary subcontractor for Amazon Air, fulfilling a significant portion of the e-commerce giant's global freight requirements. Its fleet consists entirely of Boeing 757-200 and Boeing 767-300 aircraft, selected for their ability to handle both short-haul and long-distance cargo routes efficiently. As of late 2026, the operator maintained approximately 21 aircraft with an average age of roughly 29 years, reflecting a strategy of utilizing robust airframes to maintain high utilization rates while managing costs.

In April 2021, Crane Capital acquired the airline, a transaction credited with stabilizing its financial position and enabling subsequent fleet expansion. The carrier maintains a strictly functional brand identity that avoids consumer-facing marketing or public relations campaigns typical of passenger airlines. Communication remains limited to corporate channels and industry publications, emphasizing reliability and regulatory compliance over spectacle. [edit]
