The document discusses several new features and technologies being implemented in aircraft to improve the passenger experience and reduce environmental impact, including: - Wider economy seats, more overhead storage, and optimized interior contours for passenger comfort. - Improved air filtration systems that replace cabin air every 2-3 minutes and remove 99.99% of particulate and organic matter. - Lighting and soundproofing technologies to reduce stress and jet lag on long flights. - Significant improvements in fuel efficiency and reductions in fuel burn, CO2 emissions, and noise compared to previous aircraft through technologies like redesigned sharklets and testing of sustainable aviation fuels.
