Do you bring your own snacks when flying? Don’t know what to bring? How about packing some small bags of veggies like carrots or celery, nuts or trail mix, chips, energy bar, or even some sliced chicken if you plan on eating it fairly soon? Don’t forget to add a napkin and a plastic fork. Leave the sauce, condiments, and smelly food at home, though.
You can also have an empty water bottle to get through security and fill it up at a water fountain before you board the plane.
Do you take photos of you luggage before you check it? Might be a good idea, especially if you have a stop or two.
