A recent CNN report stated that airlines are reducing fuel costs by lightening airplanes. Drinking glasses have been replaced by plastic ones, and any unnecessary item such as an old cooking oven in the stewards' area has been removed.
Last winter after being cold from our single pane sliding glass door and not having the money to replace it, we bought a large piece of polar fleece to cover the window. (It's an 6 X 8 Foot window, I looked online for the best deal and ordered 3 or 4 yards of 60 inch wide good quality fleece. I think it cost about $50.)
