I was recently looking through JetPhotos and found this cabin photo of a CA 744:

As you can see, it was taken in February this year, but the cabin hasn't been refurbished. The 744s in Air China's fleet date back to the mid-1990s. During that time CA has never even BOTHERED to refurbish their 744 cabins. Do you think they need refurbishing?
