The following items or stuff that one avoids bringing on the plane with themselves on an International flight:
Sharp objects like knives, blades, or scissors.
You should not pack any food as it may stain your clothes.
Don’t carry heavy books with you.
Don’t bring unnecessary electronic items that you don’t need.
No need to carry a lot of cash with you.
Be smart and don’t pack jewelry, as it will increase tension, and you’ll think about it the entire time during the flight journey.
