Since launching Delta One Suites in November 2017, Delta has been busy adding new Airbus A350 routes featuring what is likely the best business class cabin on a US airline. More recently, Delta began retrofitting its newest business class hard product on its 18 Boeing 777s, with the first retrofit 777 entering service in early July. Naturally, TPG was onboard to review the 777 version of the Delta One Suites.With an increasing number of Delta One Suite aircraft in the skies, there have been so many new route announcements and updates that it’s been hard to keep track.
