Your carry-on is your safety net. If a checked bag is lost, it keeps your trip going. So what should you always pack in your carry-on?
Here is the short answer. Pack anything hard to replace, plus one day of basics.
That means documents, money, medicine, and tech. Add a spare outfit too.
This guide shows the must-haves and why they matter. Do not put all your eggs in one basket.
What should you always pack in your carry-on?
The rule is simple. If losing it would ruin your trip, it goes in your carry-on.
Start with documents and money. Your passport, cards, and cash must stay with you.
Add medicine, glasses, and your phone. These are personal and hard to buy on the road.
Your hand luggage should also hold one change of clothes, just in case.
Did you know?
Liquids in your carry-on must follow the 3-1-1 rule. Each container holds 3.4 ounces or less, all in one quart-size bag, one bag per traveler.
Carry-on must-haves
A few items belong in every carry-on. Here are the ones to never skip.
See the logic? Everything vital rides with you. A lost checked bag then becomes a small problem.
Keep this bag under the seat, not the overhead bin. That way your key items stay within reach the whole flight.
What to leave out
Some things do not belong in a carry-on. Large liquids will be stopped at security.
Sharp tools and big bottles should go in checked bags. This keeps airport security quick and easy.
