I will fly with the group for the first time in a few days, and many people don't understand.

Cosmetics can't be checked, they will be found in the suitcase, and they have to be unpacked for inspection. Don't underestimate airport security.

The packaging bottle cannot exceed 100mL. Put it in a transparent bag and carry it with you.

The suitcase can be taken directly (not checked), not to mention the backpack, as long as the luggage rack is not too big.

People who travel frequently seldom like to stay.
