easyJet is introducing ultra-lightweight aircraft seats designed to reduce fuel burn and emissions while improving passenger comfort. The next-generation Kestrel seat will be installed on new Airbus A320neo and A321neo aircraft deliveries from 2028, helping deliver estimated annual savings of more than 40,000 tonnes of CO₂.
Operational impact through optimisation
The airline will become the first carrier to receive the new seats, which are manufactured by Mirus Aircraft Seating. The agreement covers easyJet’s future Airbus A320neo and A321neo deliveries as part of its order of 237 aircraft.
The seat upgrade forms part of easyJet’s broader strategy to reduce operational impact through fleet modernisation, lightweight engineering and operational efficiency measures.
Sustainability gains from lightweight aircraft design
The new Kestrel economy seat is more than 20% lighter than the seats currently used by easyJet. Its advanced lightweight structure can deliver a weight saving of up to 500kg per aircraft on larger models in the fleet.
These reductions are expected to generate annual fuel savings of more than 12,936 tonnes, equivalent to over 40,513 tonnes of CO₂.
Designed specifically for short- to medium-haul operations, the seat provides improved passenger space and comfort while contributing to reduced aircraft weight and fuel consumption.
David Morgan, Chief Operating Officer at easyJet, said:
“We are delighted to be introducing the Mirus Kestrel seat across our future fleet. This investment supports our continued focus on making our operations as efficient as possible, capitalising on small incremental gains that result in meaningful reductions in fuel burn and Co2 emissions.
On top of the sustainability benefits, the additional legroom and enhanced comfort these seats will provide will also deliver an improved onboard experience for our customers which we know they’ll love.”
Circular materials and longer lifecycle design
The Kestrel seats have been designed with sustainability and lifecycle performance in mind.
A simplified structure and low part count reduce maintenance requirements while supporting durability during long-term service. At the end of life, the seat is approximately 98% recyclable, supporting circularity and reducing waste.
Testing and development were carried out at Mirus Aircraft Seating’s UK-based MTEST facility, one of the largest commercial testing centres of its kind. Using this facility helps reduce time, cost and carbon emissions by removing the need to transport seats for external certification.
Ben McGuire, Chief Executive Officer, Mirus, said:
“Mirus is incredibly proud that easyJet, the UK’s largest airline and one of the world’s leading carriers, has placed its trust in us for what represents one of the largest single-model aircraft seat awards ever. This landmark agreement marks a defining moment for Mirus and reflects our shared commitment to enhancing passenger experience and comfort, while delivering sustainability and significant operational cost savings through reduced fuel burn and CO₂ emissions.”
Efficiency upgrades across easyJet’s fleet strategy
The seat programme is one of several engineering and operational initiatives designed to reduce aircraft weight and emissions.
easyJet recently introduced a lower-weight paint system across its fleet and has removed heavy paper flight manuals by digitising them, both of which contribute to lower fuel burn.
The airline says it continues to analyse every component of aircraft operations to achieve incremental weight savings that reduce emissions.
Fleet renewal supporting lower emissions
A key part of easyJet’s sustainability strategy is the transition to the Airbus NEO family of aircraft.
More than a quarter of the airline’s fleet is already made up of A320neo and A321neo aircraft. These newer aircraft deliver at least 13% greater efficiency and reduce noise by 50%.
The airline is gradually replacing older A319 and A320ceo aircraft with the newer models to further improve efficiency and reduce emissions.
Engineering initiatives to reduce fuel burn
easyJet is also deploying several operational initiatives designed to reduce fuel consumption and emissions.
These include installing sharklets on A320ceo aircraft by summer 2026 to reduce drag, delivering annual savings of around 308 tonnes of fuel and 970 tonnes of CO₂ per aircraft.
The airline is also implementing taxi management optimisation, combining single-engine taxiing with improved taxi-time calculations to reduce unnecessary fuel load and weight.
Additional measures include the rollout of lighter aircraft paints, expected to deliver fuel savings of 1,296 tonnes and CO₂ reductions of 4,095 tonnes once implemented across the fleet by 2030.
Other initiatives include reducing auxiliary power unit usage through pre-conditioned air units at Milan Malpensa Airport and deploying Airbus FANS-C navigation software across its A320neo and A321neo fleet to improve route planning and reduce congestion, fuel burn and delays.
From 2026, the airline will also introduce SpaceFlex cabin upgrades on a number of its 180-seat A320ceo aircraft. The configuration allows an additional row of seats without reducing passenger comfort, helping reduce easyJet’s carbon intensity per passenger.
