I'm sure by refurbishment, they mean refurbishment. That means new seat covers, fixing the fascia, maybe new carpet. That type of thing.
I think you are right. I have done about 20 long haul flights in F over the last 12 months. The product is just great. I tend to get on board and go to sleep. Its nice to wake up and have your breakfast in bed, with fresh eggs and toast etc.The cabins are getting worn for sure and I think it would be in best interest of CX to spend money keeping the cabins tip top.
If you look at some of the new business class cabins they are already showing some serious wear and tear in places.
