  • British Airlines had announced retrofitting 130 of their older A320 planes in June 2015 (link) and easyJet announced their whole fleet of 197 aircraft will be fully retrofitted by March 2018. (link)
  • United Airlines has announced, on their US website, ” ..in 2016, we began installing vortex generators on our Airbus 319/320 fleet to reduce the unique whistling sound that occurs at slower speeds due to wing design.” (link) Industry analysts have confirmed this announcement and estimate that it will take 2 years to retrofit. It is expected United Airlines will make an official announcement with more details.
  • In early 2016, US Virgin Airlines had been in discussion with Airbus about the possibility of retrofitting their fleet. This project was halted around the time of the merger with Alaska Air.
