There are several fleet cabin fit-out/refurbishment threads, and perhaps with all the activity going on improving cabin interiors it would be useful to have a consolidated thread to track new developments and progress all in one spot. Especially as new A380 and 787 operators come on line.
Some examples of a few fleets undergoing interior transition (am sure others will identify more):
Cathay’s Y+ and new business class (and progress of F conversions?)
Qantas 747 conversions
Singapore Airlines 777-3A refits
United’s progress of lie-flat J across the 777 fleet
Delta and the 744 upgrades
AA’s plans (777s)
BA’s F conversions progress
Thai’s A330s and 77Ws products
KE's 330s and 777s
Lufthansa’s new First progress, and will 748i interior be extended to other aircraft?
