Tip 1: check the carry-on luggage dimensions and weight

Make sure you check if your carry-on suitcase has the right dimensions and right weight. Every airline has its own carry-on luggage. Your suitcase can be 55x40x20cm with one airline, and only 40x30x20cm with another. The maximum weight also differs, like 8 or 10kg. Is your suitcase too large or heavy? You'll have to pay extra or it has to get checked.

Tip 2: keep the liquids in your carry-on luggage in mind

You can usually take 10 packages with 100ml of liquid in your carry-on luggage. For example, make-up, gel, deodorant, or liquid food like spreadable cheese. Put all these items in 1 transparent resealable bag of 1L maximum. This keeps your luggage clean in case something leaks and border control can see what you have right away.

Set up TSA lock carry-on luggage

Tip 3: set up your suitcase lock

Sometimes, your carry-on suitcase can't go into the airplane cabin at the last minute. You can't keep an eye on your suitcase anymore. That's why most carry-on suitcases have a TSA lock. Set this lock beforehand, so no one can just open your suitcase. Doesn't your suitcase have a lock? Take a separate suitcase lock with you.

Prohibited items carry-on suitcase

Tip 4: don't take any prohibited items with you

Check whether you don't have any prohibited items in your carry-on luggage. Are you taking a nail file, scissors, or tweezers with you? They can't be longer than 6cm. Sharp shaver blades also aren't allowed. That's why you should choose disposable shaver blades. Check the website of your airline or airport for a complete overview.
