Be sure to mention that you're a senior when you make your travel reservations. Although all major U.S. airlines except America West have cancelled their senior discount and coupon book programs, and it's not common policy in Costa Rica to offer senior discounts, don't be shy about asking for one anyway. You never know. Always carry some kind of identification, such as a driver's license, that shows your date of birth, especially if you've kept your youthful glow.
