Mention the fact that you're a senior when you make your travel reservations. Although all of the major U.S. airlines except America West have canceled their senior discount and coupon-book programs, many hotels still offer discounts for seniors. In most cities, people over the age of 60 qualify for reduced admission to theaters, museums, and other attractions, as well as discounted fares on public transportation.
