Dumb List #2: Airport Prices
They tell you to be there hours before your flight. Upon entering, they steal your water and any food you brought that they can stick their fingers in. You get forced to pay for a spot for your bags because you don’t understand their luggage fee scheme. (Aren’t they just going to misplace the bag anyway?) What to do? You are not going to stop traveling, so stop bending over and arm yourself with these secret weapons that TSA can’t confiscate with their rubber gloves.
Bring a Bottle of Water: So they won’t let you bring it through security full, but guzzle it before security and bring the empty bottle through with you. Once inside, fill it up at a water fountain. (Average savings: $3) Bonus: I board the plane with it full so I can stay hydrated throughout the flight, and many flight attendants will refill it on board.

Baggage Fees: If you fly the same carrier and earn elite status, many airlines offer these “better” customers free checked bags. Normally, it takes just 5 coast-to-coast round trips in a calendar year to earn this status. Otherwise, you can pack strategically, wearing your bulkiest clothes on the plane and minimal other items in your carry-on.

Alternately, you can ship your bags ahead of time. UPS charges their normal rates if you put your suitcase in a box, or if you give it to them as is, they charge $7.50 per bag. Just allow for travel time. And on losing parcels, UPS has a way better track record than the airlines. My friend was flying to NYC with a lot of stuff. It only cost her $100 to ship two 64-pound bags to her hotel. She checked one on the plane for $15 and was able to take the subway into the city for $7 instead of paying $60 for the cab. (Savings: Second checked bag $15, overweight fee $25, 3rd bag $100= $193 each way!) Bonus: You can also do this if you go on a shopping spree away from home. Ask the stores if they will ship it for you.
Reading Material: If you don’t have any sitting around at home, ask someone around you to borrow one. And, if you have something you have finished, ask around to see if anyone wants it. I often give them to flight attendants, who are very grateful. (Average savings $8 plus possibilities of fresh-baked cookies and little booze bottles). Bonus: You might discover we declared war on Iraq, get a strange feeling of deja-vu, then suddenly realize that you borrowed a magazine from 2003, to great relief.
Pack a Lunch: It goes without saying that airport food is pretty ordinary with a pretty hefty price tag. Even if you are pressed for time, stop at Trader Joe’s or In-N-Out along the way and get some ready-made food. (Average savings: $10) Non-Bonus: Every Guatemalan leaving

Duty Free May be Free of Duty…: and it is normally free of good deals, too. On my last trip through Brisbane Airport, MAC black liquid eyeliner was about $24 when at home, it is $16.50. Check the prices at your normal stores before you go on a trip or do a little research on the prices at your destination. I steer clear of wines and champagnes in more developing countries because they are rarely stored correctly. But I do pick up a bottle or two of Stoli vodka in Central America for around $8/liter (best price I have ever seen).

Something i recently discovered about the whole checked baggage scheme. There is this weird rule that if you have 2 checked bags with at least one piece of sporting goods in each the second bag is free to check. I use a scuba mask in one bag and a snorkel in the other. The last time i flew they had no idea what i was talking about and instead of looking it up they just gave me both bags for free.
