Can I wear a mask or something when I fly?

At present, all major airlines stipulate that the liquid content in carry-on baggage (not checked) should not exceed 100ml. The volume of a general sheet mask (individually packaged) is about 30ml, which will not exceed 100ml and can be worn.

As for why the liquid above 100ml can't be brought on the plane, it's because someone brought the liquid on the plane before, which led to the plane crash. After research, it is considered that the liquid below 100ml cannot pose an explosion threat, so it is now allowed to carry the liquid below 100ml.

If you bring a lot of masks, you will also be asked to check them in. Especially when buying a large number of masks in Taiwan Province Province, the total amount of masks exceeds 1L and is required to be inspected by prosecutors, which happens from time to time. If it's just a long flight and you are afraid of dry skin, you can bring one or two bags of masks with a size not exceeding 100ml.

Extended data:

If you are a passenger with children, milk and milk powder must be checked and it is impossible to enter the security check. If you need to drink on the plane, ask when you buy the ticket, and the flight attendant will provide it.

Liquid medicine, if you are seriously ill, you must take these medicines with you. You have to go to the hospital to get a hospital certificate approved by the airline. When buying a plane ticket, you should ask what airline you are buying. Each airline has different requirements. Without evidence, we can only pack and check.

Generally, only one person is allowed to take two pieces of luggage on the plane, depending on the size of the seat. One piece can be placed in the chassis above the seat and the other can be placed under the foot. That means a small suitcase and a carry-on backpack.
