Is it okay to eat a granola bar on an airplane?

It depends. If you are flying during meal service, you should check with the airline for their specific policies regarding food and beverages. Generally speaking, most airlines permit passengers to bring snacks onto planes, as long as they meet certain guidelines such as being sealed or packaged in a way that prevents them from spilling or leaking. However, some airlines may have restrictions on what types of foods and drinks can be brought on board.
