Buying snacks in the airport is incredibly expensive. By planning ahead and making sure that you bring your own granola bars and sweet treats, you can save a good bit of money.
This is especially true if you have specific dietary restrictions, such as eating only a certain type of granola bar or needing to find quality vegetarian or vegan options.
Another hack is to bring an empty water bottle with you on your trip. We all know you can’t bring liquids through airport security, but you can bring a bottle.
The airport is full of free water filling stations, usually by restrooms. This will save you from spending three dollars for a water bottle while waiting for your flight.
