In the transportation services trio of planes, trains and automobiles, discounts have all but vanished in the first category, but you can still find plenty of deals on the other two.
Smidt notes that Southwest Airlines seems to be the only airline actively promoting a senior discount program.
"The benefit with the senior discount at airlines is that the tickets are usually fully refundable, and there may not be change fees," Smidt says. "So while the discounts may not be substantial, they provide some flexibility."
Amtrak offers a 15 percent senior discount on the lowest available fare for passengers 62 and older on most trains. For travelers going across the Canadian border on trains operated jointly by Amtrak and VIA Rail Canada, a 10 percent discount applies to those 60 and older.
SeniorDiscounts.com and AARP have partnerships with various car rental companies to offer discounts. The AARP website, for example, lists discounts of up to 25 percent. AARP also offers free upgrades on Avis, Budget and Payless car rentals.
To make sure you're getting the most savings, check travel websites and compare their best rates with the ones you get when you call the car rental companies and ask for their senior discounts.
