No doubt you are correct about the fabric actually being leather,
usairways lover - I only looked at them in passing - and they may well be the newest planes in the fleet. However, the seats definitely looked old, not least in their design - very simple, basic and dated looking, without even an adjustable headrest - and the pale grey substance that the seats were upholstered in looked dingy and not very clean. As I said, I never actually got to try one out, so it could be that appearances are deceptive.
Edited to add: this was the type of seat I'm talking about

You are indeed right that it's leather, but doesn't that seat look like a relic of the 70s? Or is it just me?!
