Carry-on luggage is not for taking "everything valuable". It is for keeping with you the things that would ruin the trip if you lost access to them in the airport or during the first hours after arrival. The basic rule is simple: documents, medicine, tech, essentials, and nothing that will create trouble at security.
What is actually worth packing
- Documents, phone, charger, wallet: everything you need for check-in, boarding, and getting to your accommodation.
- Medicine you may need on the way: especially anything you cannot simply replace later.
- A power bank, headphones, and cables: these are often most useful during the trip itself.
- A small backup set of clothes: a T-shirt, underwear, or an extra light layer can save the day if checked baggage is delayed.
What is better not to pack there unless needed
- Items restricted by the airline or security rules: they can cost you both time and the item itself.
- Large containers of liquids: this is a common problem at security screening.
- Sharp objects: even a small everyday item can be disallowed in the cabin.
- Too much "just in case" stuff: an overfilled carry-on quickly becomes uncomfortable and inconvenient.
Useful details
- Power banks are usually kept in carry-on: battery transport rules often treat them separately.
- Rules can differ: before flying, it is better to check the requirements of your airline instead of relying only on someone else's experience.
- The best carry-on is organized logically: the most important things should be easy to reach, not buried at the bottom.
