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.

New York subway and bus fares are half-price ($1) for people 65 and older. Many museums and sights (and some theaters and performance halls) offer discounted admittance and tickets to seniors, so don't be shy about asking. Always bring an ID card, especially if you've kept your youthful glow.

Many hotels offer senior discounts; Choice Hotels (which include Comfort Inns, some of my favorite affordable Midtown hotels), for example, gives 30% off their published rates to anyone over 50, provided you book your room through their nationwide toll-free reservations number (that is, not directly with the hotels or through a travel agent).
