Can I bring snacks on a plane?
Yes. My mother-in-law always brings stuff. I think it’s frowned upon, but as long as it’s not any kind of nut, you’re fine. Sour Patch Kids would be fine. Good choice, since they’re good if you get bothered by the air pressure change (my ears hurt the whole time I’m in the air, but most people are only bothered on take-off and landing). Bring gum, too!
