Emirates has reached a symbolic milestone in its massive cabin modernization program, with 100 aircraft already retrofitted – an operation presented as the largest ever undertaken internally by an airline. In less than four years, Emirates will have completely renovated 47 Airbus A380s and 53 Boeing 777s, while installing a Premium Economy cabin on every aircraft. **An unprecedented industrial project** Launched operationally in November 2022, the program has upgraded 100 widebodies in 44 months, averaging about 28 aircraft per year. Emirates Engineering teams mobilized over 400 engineers and technicians, totaling 4.4 million work hours to dismantle, refresh, and reconfigure cabins before returning each aircraft to service. According to the airline, this is "the largest retrofit program known globally, carried out entirely in-house" – a strategic move as its order book, particularly for the 777X, faces delays. "Our commitment to offering top-tier products in every cabin is an ongoing endeavor, and completing the full retrofit of 100 widebodies in 44 months is a significant achievement," said Sir Tim Clark, President of Emirates Airline. "Backed by a $5 billion investment, this project ensures our customers 'fly better' with a superior level of luxury, comfort, and attention to detail in every cabin," he added, emphasizing the planning, precision, and expertise required to carry out this project entirely in Dubai. **Premium Economy deployed at scale** Each aircraft that passed through the hangars was equipped with a new Premium Economy cabin, installed alongside existing cabins. Emirates reports having installed more than 3,800 Premium Economy seats, accelerating the rollout of this intermediate product on an increasing number of long-haul routes. On the A380, introducing Premium Economy on the upper deck required structural modifications and a new class distribution, as illustrated by the recent retrofit of an A380 from two to three classes completed in May 2026. Emirates also claims a gradual homogenization of the cabin experience across its fleet, with refreshed seats in First, Business, and Economy, new carpets, and revised color palettes. The stated goal is to ensure passengers find a comparable level of comfort regardless of the aircraft's age. **Retrofit engineering: from hangar to tarmac** Each project begins with the near-complete dismantling of interior fittings, with engineers working on over 4,000 parts for an A380 and over 2,500 for a 777 before reassembly. To manage this volume and logistical complexity, Emirates Engineering developed specific solutions, such as modified catering trucks to move large parts between the retrofit workshop and the aircraft, and zonal tracking systems for work progress. The team also designed and built dedicated equipment to access all interior areas and handle components, relying on a network of over 100 supplier partners. Over the months, project times were optimized, with a target of 21 days for an A380 and 18 days for a 777 for a complete retrofit. By the end of December 2026, Emirates plans to exceed half of the 219 aircraft planned, with about twenty additional aircraft modernized by the end of the year. From October 2026, a new phase will see the installation of 4K OLED HDR10+ screens on seatbacks and new lighter Safran Z400 seats, along with other cabin evolutions and connectivity improvements, notably via Starlink Wi-Fi. **A sustainability component: upcycling** Alongside this industrial project, Emirates highlights an environmental aspect with high-end recycling of cabin materials, transforming them into objects of higher value. Thousands of kilograms of leather, textiles, and other materials removed from retrofitted A380s and 777s are turned into limited-edition collectibles, including luggage under the "Aircrafted by Emirates" brand. The airline also designed "Aircrafted KIDS" backpacks from Economy seat fabrics, distributing over 4,000 to children in 11 countries across Africa and Asia. According to Emirates, more than 50,000 kg of materials are expected to be recovered and reused over the 219 planned retrofits. This approach is part of a broader set of sustainability initiatives that have earned the Emirates Group new distinctions in environmental footprint reduction and recycling.
