Whenever I travel I park my own car at the airport, but I save money by using the satellite lots near the airport. Their shuttle buses pick me up immediately and drop me off at the terminal, which is more covenient than parking on-site at the airport and walking all the way across the parking lot to the terminal.
Not only are the satellite rates less expensive, but you can always print coupons for my favorite lots. And if your lot doesn’t have a coupon available, call the lot you like and ask if they accept competitors’ coupons. Mine does, so I find the best one available for my trip length and save at least $10 and up to $30 simply by printing one piece of paper. Between business and family trips we save quite a bit over the year.
My favorite site for airport parking coupons across the country is www.longtermparking.com . Check it out!
