Avia Solutions Group to complete one of the world’s first Boeing 777-300ER passenger-to-freighter conversions

Jul 07, 2025

AviaAM Leasing Service Centre (AviaAM Leasing), an Avia Solutions Group company specializing in tailored aircraft leasing and trading services, is entering the final stages of a unique project – Boeing 777-300ER passenger-to-freighter (P2F) conversion. 

The project is being carried out in collaboration with US-based Mammoth Freighters LLC, which specialises in Boeing 777 P2F conversions. The conversion is expected to be completed by the end of this year.

“This type of conversion of a popular passenger aircraft is a historic achievement for AviaAM Leasing. Boeing foresees air cargo operators will need more than 2,600 freighters over the next two decades to keep up with increasing global freight traffic. P2F conversions are one way to meet this growing demand,” says Jonas Janukėnas, CEO of Avia Solutions Group.

“Once converted, the Boeing 777-300ERMF will be one of the most fuel-efficient long-range freighters available. Its impressive payload capacity and range make it an attractive option for cargo operators worldwide,” says Brian McCarthy, Vice President of Sales and Marketing at Mammoth Freighters LLC.

Tadas Goberis, CEO of AviaAM Leasing, emphasizes the project’s significance: “This represents the world's first aircraft of this type – a prototype that marks a significant milestone in our company's growth. We plan to convert several additional aircraft of this model in the near future. This project will help us strengthen our position in the cargo aircraft leasing sector, as these converted aircraft will enable logistics companies to expand their capacity. “

A Boeing 777-300ER can carry nearly 400 passengers in a standard two-class layout. Once converted, it will be capable of transporting up to 98 tonnes over 5000 nautical miles with substantial volume of 819 cubic meters of cargo on long-haul routes, including transatlantic operations.

AviaAM Leasing, which provides commercial aircraft leasing, trading, and administration services, has already completed over 150 aircraft transactions as well as more than 50 aircraft conversion and refurbishment projects. The company is among the top 50 leaders in the aircraft leasing market.
