Mention the fact that you're a senior when you make your travel reservations. Although most of the major U.S. airlines have canceled their senior discount and coupon book programs, many hotels still offer lower rates for seniors. In most cities, people over the age of 60 qualify for reduced admission to theaters, museums, and other attractions.
