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 60 and over qualify for reduced admission to theaters, museums, and other attractions, as well as discounted fares on public transportation.
Members of AARP (formerly known as the American Association of Retired Persons; tel. 888/687-2277; www.aarp.org), get discounts on hotels, airfares, and car rentals. Whether or not they end up being better than the regular discounts is an open question. Always do your research before buying.
