Generally, solid foods like sandwiches, fruits, and granola bars are allowed in your carry-on bag. However, liquids and gels are subject to the 3-1-1 rule, which means they must be in containers of 3.4 ounces or less, and fit in a clear quart-sized ziplock bag. It's like packing a lunchbox for school, but with more rules!
But, what about hot foods like pizza or fried chicken? Sorry, folks, those are usually a no-go, as they can be messy and smelly. You don't want to be that person who clears out the entire plane with their stinky food!
And, let's not forget about perishable items like meat, dairy, or eggs. These are usually not allowed, as they can spoil easily and make a mess. You wouldn't want your in-flight snack to turn into a science experiment, would you?
