Top 10 Cargo ACMI Providers in 2026: Freighter Wet-Lease Operators

Atlas Air remains the reference point for large-scale outsourced freighter operations. The US carrier has built its business around ACMI, CMI and charter flying and operates cargo programs for airlines, logistics companies, express operators and major multinational customers.

Its importance comes from both fleet scale and operational infrastructure. Atlas can support long-term dedicated operations across multiple continents, including high-capacity intercontinental flying using Boeing 747 and 777 freighters and lower-capacity missions using the 767 platform.

Atlas also has extensive experience operating aircraft dedicated to individual customers. That makes the company particularly relevant where a shipper, airline or logistics group wants aircraft capacity integrated into its own branded network rather than simply buying individual charter flights.

ASL Aviation Holdings has one of the deepest positions in contracted cargo flying, particularly in the express, postal and e-commerce sectors. Its airlines have long operated aircraft on behalf of major logistics networks rather than relying exclusively on scheduled cargo sold under ASL's own commercial brand.

The group is particularly notable for its Boeing 737 freighter platform, including a substantial 737-800BCF operation, giving customers access to narrowbody capacity suited to overnight express networks and regional cargo flows.

ASL has also expanded its long-haul ACMI capability. Its 2025 agreement to wet lease A330-300P2F aircraft to Saudia Cargo illustrates the group's ability to move beyond regional express flying into higher-capacity international cargo operations.

Air Atlanta is one of the longest-established specialist ACMI operators in the market. The Icelandic group has spent decades operating aircraft for other airlines and is particularly associated with complex widebody deployments.

Cargo remains central to the operation. Air Atlanta's freighter fleet includes Boeing 747 and 777 aircraft, giving it a natural position in long-haul cargo markets where customers need substantial payload capacity without committing capital to widebody ownership.

The company became even more strategically significant in 2026 when Atlas Air Worldwide completed the acquisition of a 49% stake in Air Atlanta. The transaction links two of the industry's most experienced outsourced widebody operators while Air Atlanta continues to operate independently.

Kalitta Air combines large-aircraft cargo operations with its own maintenance infrastructure, giving the US operator an unusually integrated operating model.

Its commercial cargo business explicitly includes long-term charter programs, ACMI and on-demand charter services. The carrier operates Boeing 747-400F and 777 freighters and serves freight forwarders, government customers and other organizations requiring substantial long-range lift.

Kalitta's own heavy-maintenance and engine-overhaul capabilities are particularly relevant in an ACMI context. Technical control and aircraft availability can become decisive when a customer is committing to a multi-month or multi-year dedicated operation.

Cargojet is one of the most important outsourced cargo operators in North America. The Canadian carrier operates domestic overnight flying while also maintaining dedicated ACMI and international charter businesses.

That combination gives Cargojet a strong position where customers need repeat, time-critical sectors integrated into larger express or e-commerce networks. Its ACMI operations have included cross-border routes connecting Canada, the United States, Mexico, Central America, South America and other international markets.

Cargojet's established overnight network also gives the operator substantial experience with the tight aircraft utilization, sort-window discipline and schedule reliability required by parcel and express customers.

National Airlines offers dedicated ACMI and CMI alongside its substantial cargo charter business. Its model is geared toward customers that need fully operated freighter capacity placed directly into an existing network.

The carrier markets Boeing 747 and 777 freighter capacity for cargo operators, freight networks and integrators. It also maintains a 24-hour systems operations capability covering dispatch, crew scheduling, AOG response and parts support.

National is especially relevant when the requirement involves unusual routing, heavy freight or an operation that needs to move between charter and longer-term dedicated capacity.

ABX Air is a specialist Boeing 767 cargo operator and one of the most established names in outsourced express flying in the United States.

Its ACMI offering provides the aircraft, crews, maintenance and aircraft liability insurance under either short- or long-term arrangements. The airline's concentrated 767 fleet is particularly relevant for customers that do not require the payload of a 747 or 777 but still need widebody containerized cargo capability.

ABX's background in overnight express logistics also makes it well suited to repeat scheduled operations where aircraft reliability, precise departure windows and network consistency matter more than ad-hoc charter flexibility.

Challenge Group has developed an integrated air cargo platform around airlines in Belgium, Malta and Israel, supported by handling, logistics, maintenance and commercial subsidiaries.

Challenge Airlines BE specifically operates as a full ACMI provider within the group using Boeing 747-400 freighters. Challenge Airlines MT adds Boeing 767-300F capacity, increasing the group's flexibility across different cargo volumes and route structures.

Its European AOCs, Liège presence and associated handling infrastructure make Challenge particularly interesting for cargo programs built around Europe, the Middle East, Asia and transatlantic lanes.

Western Global Airlines is a US all-cargo carrier focused heavily on contracted transportation. Its services range from ACMI to dedicated full-service operations for customers in express freight, e-commerce, forwarding, government and humanitarian logistics.

The carrier's operating model is designed around deploying large freighters internationally rather than maintaining a conventional passenger-airline-style network. That makes Western Global relevant where the aircraft needs to follow the customer's cargo flows.

The company reports operations across hundreds of airports and markets its ability to structure dedicated cargo programs around customer requirements.

Astral Aviation gives the list an important African operator. Based in Nairobi, Astral combines scheduled cargo services, charter flying and ACMI using Boeing 767 and 737 freighters.

The carrier has built a broad African network supported by hubs and operating points connecting the continent with the Middle East and Europe. Its fleet mix is useful because customers can deploy capacity according to the density and range of a particular African trade lane rather than defaulting to very large intercontinental freighters.

Astral is also experienced in specialized commodities including perishables, pharmaceuticals, dangerous goods, mining cargo, oil and gas equipment and humanitarian freight.
