The global air cargo industry is leaning hard on converted Boeing 777 passenger jets to fill a widening freighter gap, but the pool of used airframes is drying up as airlines hold onto widebodies longer. Three conversion programs are now competing for a shrinking supply of 777-300ERs that are young enough and structurally sound enough to modify.
The Numbers Driving The Scramble
Cargo tonne-kilometres grew 5% in the first nine months of 2026 while capacity grew just 1.7%, according to IATA data cited by Stat Times. September alone saw demand jump 7.7% against 2.7% capacity growth. The value of AI-related goods shipped by air surged 20% in 2025, accounting for 53.5% of air trade by value but only 7% by volume. That density drives demand for large widebody freighters — exactly the segment where new production is late.
New Jets Slip To 2027 And Beyond
Airbus expects EASA certification for the A350F in 2027 with first deliveries in the second half of that year, a two-year slip from its original 2025 target. The A350F carried 115 firm orders at the end of August 2026, led by Atlas Air with 20. Boeing’s 777-8F first delivery has moved from 2027 to around 2029. The program held 89 firm orders in October 2026, including 34 from launch customer Qatar Airways, ten from Cargolux and eight from Ethiopian Airlines. The 777-8F offers a maximum structural payload of 118 tonnes versus 111 tonnes for the A350F.
Used 777 Supply Is Tightening
Passenger airlines are retaining 777-300ERs longer because delays to the 777X family have disrupted replacement plans. The 777-9 flight-test team landed in Iceland in November 2026 as part of testing ahead of a planned 2027 first delivery. Over 2,300 777s have been ordered across all variants, making it the most-built widebody, but the conversion market needs airframes in a narrow age and condition window. Conversion specialists report they must compete for a relatively small number of aircraft that are economically viable to modify.
Conversion Economics Face Scrutiny
Converted 777s offer substantial payload without the wait for a new-build freighter, but their fuel consumption, acquisition costs and remaining service lives raise questions about long-term commercial viability. The 777-300ER’s large fuselage and structural capability make it attractive for conversion, yet the aircraft burns more fuel than the coming A350F and 777-8F. Airbus projects the A350F will burn about 20% less fuel than the current 777F and 40% less than the 747-400F. Boeing argues the 777-8F will burn less than the A350F at equal tonnage.
Stopgap Orders Fill The Near Term
Boeing and Icelease signed an agreement on October 22, 2026 for one 767-300BCF with options for two more. Induction is scheduled for Q1 2027 with delivery in Q2 2027 after conversion at ST Engineering’s Singapore facility. The 767-300BCF carries a 57-tonne payload to a range of 3,300 nautical miles. Icelease’s Dublin-based sister company IAT Leasing already manages seven 737-800BCFs and other freighters for various customers. The 767 conversion is a proven performer, but it is a medium widebody — not a direct substitute for the large widebody capacity the market is missing.
