Pack with prudence

Travel can be an expensive habit, but it’s one I don’t want to give up. This year I’m looking to cut corners, beginning with my usual point of departure: the airport. With a little planning I can pack a light snack that probably is healthier than what I would grab on the go ($10). I can carry an empty water bottle through security and fill it at a water fountain ($2). Taking the subway instead of a taxi to the airport isn’t all that hard and the cost difference is enormous ($38). If I pack carefully I won’t have to check my bag ($15). I can bring my own headset ($2), and instead of paying for a pillow and blanket ($7), I can carry my thin wool pashmina to use if I get chilly in flight. Round-trip savings: $128.That’s almost the price of a one-way flight to ... somewhere.
