I’m a big fan of free. Especially at the airport. So here are a few of the items I included in a slide show of great airport promotions that I put together for CNBC Road Warrior.

Volunteers at Indiana’s Fort Wayne International Airport welcome arriving passengers with a cheery greeting and a complimentary cookie baked and individually wrapped by nearby Ellison Bakery. They’ve been doing this since sometime in the late 1980s and, by December 2009, handed out their 1 millionth cookie. Don’t worry if you’re too late to get a cookie from one of the treat-toting Hospitality Hosts; there’s an after-hours self-service cookie stand.

On both Mother’s Day and Valentine’s Day, volunteers at Jacksonville International Airport hand out more than 1,000 colorful carnations to passengers.

The parking promotions at Oakland International Airport is a very nice, money-saving perk. Through April 15, travelers leaving from OAK on any airline heading to any destination in Hawaii or Europe can get up to five days’ free parking (worth up to $110) in the airport’s Daily Lot. Passengers flying to any destination in Texas can get free parking (up to $66) through April 15 as well.
