YES, there are new interiors on the West side. All of our newer A319-20's have leather seats, not covers, upgraded f/c leather seat with better pitch and headrests. They are extremely comfortable compared to our space savor airbus seats with fabric covering. It is to my understanding they are replacing all older seats on East and West to the new leather covering, whether it be a "cover", or complete new seat, we shall see?? All of our 73's and 75's have the older teal fabric seat covers, and need to be upgraded to the pleather or leather. :huh:There are no full new interiors currently in our a/c, that will begin sometime in the next two months, probably November will begin the process. Two configurations of the B757 are probably attributed to the lower revenue yield for certain markets.
