Honeywell Auxiliary Power Units Selected by Jet2.Com for Its New A321NEO Airbus Fleet

 Honeywell’s 131-9A APU provides high performance, low maintenance and fuel savings for single-aisle Airbus aircraft

PHOENIX, Oct. 20, 2022 –, the award-winning leisure airline that specializes in scheduled holiday flights, and Jet2holidays, the UK’s leading provider of package holidays to leisure destinations across the Mediterranean, Canary Islands and European Leisure Cities, have selected Honeywell (NASDAQ: HON) to equip up to 75 aircraft in its new Airbus A321 NEO fleet with auxiliary power units, as well as provide aftermarket support.

An auxiliary power unit (APU) is a critical piece of aircraft equipment that provides electrical power and air conditioning while the plane is on the ground to ensure increased passenger comfort and supplies the air source when a pilot is ready to start the main engines. The selected Honeywell 131-9A APU will be equipped with Honeywell’s High Efficiency Modification (HEM) upgrade for single-aisle Airbus aircraft, with improved compressor efficiency. Honeywell’s 131-9A has been continually developed to lower fuel consumption and reduce the carbon footprint of aircraft while also increasing its time-on-wing leading to fewer shop visits over the life of the unit.

Under the terms of the agreement, will also use Honeywell’s Predictive Trend Monitoring and Diagnostics application (PTMD) to reduce maintenance costs and improve the process of troubleshooting Honeywell APUs. Maintenance of the APUs will be performed at Honeywell’s facility in Raunheim, Germany. is the third-largest scheduled airline in the United Kingdom and is also the second-largest tour operator in the United Kingdom. To support its growth, have invested in ambitious fleet expansion and renewal plans, including the purchase of up to 75 new Airbus A321 NEO aircraft.

Honeywell’s first APU took to the skies in 1950, and the company has built more than 100,000 since then.

More than 36,000 APUs, including both fixed wing and rotary wing, are in service today across more than 150 regional, executive, commercial and military applications.

In 2009, the Honeywell 131-9A APU on an Airbus A320 played a critical role in the emergency landing of US Airways Flight 1549 in New York’s Hudson River, in which all 155 passengers and crew survived. Honeywell has shipped more than 15,000 131-9A APUs since introducing this model in 1995.
