The most common surprise is water: ordinary liquids are generally not allowed in hand luggage on a domestic flight, while limited travel cosmetics, toothpaste, shaving cream, essential infant food, and medically necessary liquids follow specific conditions. Do not assume the international 100 ml bag rule works in exactly the same way.
Move these out of hand luggage or leave them
- Drinks and ordinary liquid containers.
- Knives and other sharp items that may be checked but not carried in the cabin.
- Alcohol, which must meet checked-baggage conditions.
- Lighters, matches, ignition devices, and self-heating food, which CAAC lists as prohibited.
Keep these out of checked baggage
- Power banks and spare lithium batteries.
- Cash, jewelry, passports, and valuables.
- Fragile electronics and essential medication where airline rules permit cabin carriage.
Domestic flights also apply current CCC and recall restrictions to power banks. Check the mark on the device, not only the box.
