The cost of in-flight snacks can be painful. A la carte items — say a mini-can of Pringles — can cost $2.50. Snack packs, with miniscule amounts of items you may not even like, are $6 to $8. If you’re traveling with your family, the cost of snacks can set you back the price of checking a bag. Here’s a cheaper way to deal with in-flight hunger: Bring your own snack pack. A few days before your flight, hit the dollar store. We found nuts, raisins, crackers, cookies and — yes! — chocolate bars in single-portion, individually wrapped packets for just a buck. If you get one package of each, you will be out only $4. Of course, you can add more items depending on the selection and your own preferences. Assemble your own “snack pack.” Use a rigid resealable container to hold your snacks. If you’re traveling with others, make a snack pack for each one. If you’re flying solo, throwsome extra packs into your carry-on — there’s no telling when a flight might be delayed or you might be stuck on the tarmac for hours or when you mig need a pick-me-up at your destination. Either way, you’ll come out way ahead on those pricey snacks the airlines would love to sell you.
