What difference can an ounce make on an airplane?
If you are United Airlines, with 4,500 flights a day, an ounce can add up. The Chicago-based carrier said it recently began printing its inflight magazine, Hemisphere, on lighter paper, cutting 1 ounce from each magazine. It now weighs 6.85 ounces.
In an internal message to employees, United said it has also switched to lighter paper on its seatback service guides.
