Dutch carrier KLM has debuted a cabin upgrade for the first of 14 Boeing 737-800s, part of a fleet revamp it aims to complete by March next year.

The refurbished aircraft, which are mostly deployed on European flights, have new seats in economy and business classes. The seats are around 20% lighter than previous seats, contributing to estimated annual savings of 58 tonnes of fuel and 184 tonnes of CO2 emissions per aircraft.

The upgraded cabins also have onboard connectivity, USB ports for charging devices, and larger overhead bins.

KLM executive vice-president customer experience Boet Kreiken, says: “KLM wants to offer its passengers even more comfort and style on European flights, while reducing the CO2 emissions of flights. That is why KLM continues to invest in its onboard product and sustainability, so we can continue to meet our customers’ expectations and emerge stronger from the crisis.”

The work is being completed by KLM’s Engineering and Maintenance division.
