We are also taking steps to use more sustainable materials — and, in particular, to find ways to reduce single-use plastics — as part of our onboard products and meal service. While adjustments made in response to COVID-19 presented challenges in advancing some of our sustainable materials goals — such as providing bottles of water rather than refilling cups to minimize contact — we have tested a number of new products over the past two years that we are aiming to roll out more broadly. For example, in 2021 we piloted a sustainable cutlery kit made out of bamboo. We also began offering a sustainable meal box, which is a fully compostable box with prepack - aged snacks, across our regional operations. In addition, we introduced new onboard amenity kits for premium cabin customers in partnership with Shinola and D.S. & Durga, which include a number of sustainability features. For example, the dental kit and ear plugs are individually packaged within a biodegradable wax paper instead of single-use plastic, and the toothbrush is made from wheat straw instead of plastic. Alongside these onboard efforts, we have instituted a number of sustainability improvements in our lounges. They include switching from plastic to compostable flatware and straws, installing water bottle filler stations, testing reusable to-go bags and more. Reducing Aircraft Noise We recognize and are committed to addressing the ongoing concerns of local communities regarding aircraft noise. One way we have done this over the past few years is by voluntarily retrofitting our aircraft with fuel vent vortex generators (VGs). These fairings are installed around the wing fuel tank over the pressure vent, on the underside of the wing of the A320 family of aircraft. These vents reduce airframe noise during portions of the approach by an estimated four to six decibels. Prior to 2014 deliveries, Airbus did not equip aircraft with VGs — so American has invested over $1 million to retrofit our pre-2014 aircraft with this feature. By April 2022, we had modified 290 narrowbody pre-2014 aircraft with retrofit VGs, meaning all Airbus aircraft in our fleet now have the VGs utility. We also continue to meet or exceed ICAO noise certification standards, which currently specify that operators can fly Stage 3, Stage 4 or Stage 5 aircraft. All of American’s mainline and regional fleet meet Stage 4 noise certification levels, and 20% meet Stage 5 noise certification levels.
