The inside as in seats are generally OK but if you look around doors and partitions they are tired A/C, though as you say well maintained. Also I agree BA also have A/C of similar age to some of Jet 2 A/C though I have to say when I used to fly BA, I did not come across one which appeared to have paint applied by brush strokes rather than spraying on the inside of the cabin, as I did last year on an old 737- 400 into Man.
