<h1>Airline Launches $400M Retrofit Program for B787-8, 777-300ER, A320neo, and A321ceo Aircraft Upgrades</h1> An airline announced a $400 million retrofit program to upgrade avionics and critical components of 26 legacy B787-8 aircraft to enhance reliability and reduce operational disruptions following a fatal crash involving one of its planes. The upgrades, based on manufacturer service bulletins, include maintenance record analysis and implementation of recommended modifications. Seven aircraft will undergo heavy maintenance checks, with retrofits expected to complete by mid-2027. The retrofitted planes will feature a three-class seating configuration. Additionally, the airline plans to retrofit 13 legacy Boeing 777-300ER aircraft by October 2028, delayed due to supply chain issues. The program also includes retrofitting 27 legacy A320neo aircraft, with completion anticipated by September, and a decision to retrofit 13 legacy A321ceo planes previously slated for retirement.
