While it’s taken them a long time to get started replacing current cabins with new ones, the first plane – a 25 year old Airbus A319, registration N801UA – is in the shop for the retrofit.
The project will finish in less than 3 weeks, and then a 25 year old Airbus A320 goes in for work. Together these two will serve as prototypes for their respective fleets. And a photo of the retrofit process has leaked.
