Ethiopian Airlines Leases Two 777-300ERSF Freighters for 2028 Delivery

Ethiopian Airlines is set to become the first carrier in Africa to operate the Boeing 777-300 Extended Range Special Freighter (777-300ERSF), the largest twin-engine cargo aircraft in operation. The carrier has signed a lease agreement with lessor AerCap for two of the converted freighters, with deliveries scheduled to begin in the second quarter of 2028. The move signals a significant expansion of Ethiopian Airlines' cargo capacity and modernizes its fleet with a more fuel-efficient platform.

The agreement deepens the existing relationship between Ethiopian Airlines, AerCap, and Israel Aerospace Industries (IAI), the company that developed and performs the passenger-to-freighter (P2F) conversion. This partnership has previously seen the successful conversion of several Boeing 767-300ER aircraft for the airline. By adopting the 777-300ERSF, marketed as 'The Big Twin', Ethiopian Cargo is positioning itself to handle growing volumes of e-commerce and general freight across its global network.

According to Ethiopian Airlines Group CEO Mesfin Tasew, the new aircraft will significantly enhance the airline's cargo capacity and operational efficiency, which is critical for boosting regional trade. AerCap CEO Aengus Kelly noted the aircraft's cost efficiencies and its 25% increase in cargo volume over smaller twin-engine freighters as key advantages for Ethiopian's logistics network.

The 'Big Twin' Enters Africa

The lease agreement with AerCap makes Ethiopian Airlines a key African customer for the 777-300ERSF program. The aircraft's entry into service was pioneered by U.S. carrier Kalitta Air, which became the launch operator in September 2025 after taking delivery of the first two converted airframes from AerCap. Ethiopian's commitment validates the growing market demand for large-capacity converted freighters as a cost-effective alternative to new-build cargo aircraft.

The conversion program itself achieved a critical milestone in 2025 when it received its Supplemental Type Certificate (STC). This regulatory approval was granted jointly by the Federal Aviation Administration (FAA) of the United States and the Civil Aviation Authority of Israel (CAAI), clearing the engineering design for global commercial operations.

For stakeholders, the deal has clear benefits. Ethiopian Airlines gains a competitive edge in capacity and efficiency. AerCap secures a marquee African client for its P2F program, and IAI expands the operational footprint of its certified conversion. The move also intensifies competition for Boeing's production freighter division, as the cost of a converted 777-300ERSF is roughly one-third that of a new factory-built freighter, offering comparable performance for specific cargo missions.

B777-300ERSF vs. Legacy Freighters: Key Specifications

The primary advantage of the 777-300ERSF is its immense volume, optimized for lower-density e-commerce cargo. While its maximum structural payload is slightly less than a new production 777-200F, its stretched fuselage provides significantly more space.

Technical Analysis

This agreement represents more than a simple fleet update; it is a strategic alignment with major industry trends. The adoption of the 777-300ERSF reflects a broader shift away from aging, fuel-intensive four-engine freighters like the Boeing 747-400F. According to IAI specifications, the 'Big Twin' burns 21% less fuel per tonne compared to the 747-400F, a critical efficiency gain in an era of high fuel costs and environmental pressure. The aircraft's massive 819 cubic meters of cargo volume is particularly well-suited for the e-commerce market, which often involves bulky but relatively light goods.

Ethiopian's decision follows the successful precedent set by Kalitta Air's entry into service, demonstrating the reliability and operational readiness of the IAI conversion program. By leveraging a converted airframe, the airline can significantly expand its main deck capacity at a fraction of the capital cost of a new production freighter like the Boeing 777-8F. This move solidifies the role of P2F programs as a central pillar of fleet strategy for cargo operators seeking to balance capacity growth with capital discipline.

What Comes Next

The primary milestone for this agreement is the scheduled delivery of the first aircraft to Ethiopian Airlines. According to the announcement from AerCap and the airline, the first of the two 777-300ERSF jets is confirmed for delivery in the second quarter of 2028. The second aircraft is expected to follow shortly thereafter. Between now and then, IAI will perform the complex P2F conversion on two mid-life Boeing 777-300ER passenger aircraft sourced by AerCap.

Why This Matters

Ethiopian Airlines' acquisition of the 777-300ERSF solidifies its position as a leading cargo operator in Africa and a significant player on the global stage. The move demonstrates a clear strategy to dominate the growing African air freight market by leveraging the most efficient high-volume freighter available. For the broader industry, it accelerates the transition to twin-engine freighters and cements the success of the IAI 777-300ERSF conversion program as a viable and competitive alternative to factory-built cargo aircraft.
