As the demand for winter travel increases, many passengers carry hot water bottles and other warming items on board, but the regulations for carrying such items often cause confusion. This article will, in combination with civil aviation safety regulations, provide you with a detailed answer to the question of whether hot water bottles can be taken on a plane.

I. Types of Hot Water Bottles and Flight Regulations

Traditional filling hot water bag

If there is no liquid in the bag, it can be carried with you or checked in. If it contains water, it must be emptied in advance to pass the security check; otherwise, it can only be checked in.

Electric hot water bag (including liquid type)

Due to the potential safety hazards caused by changes in internal liquid pressure, civil aviation regulations prohibit carrying it on board, but it can be checked in. Please note: If the liquid composition is unknown or contains flammable substances, consignment is prohibited.

Electric heating cake (Solid heating type)

If the label is clear and the rated energy is ≤100Wh, it can be carried around. Exceeding 100Wh requires approval from the airline, with an upper limit of 160Wh.

Ii. Suggestions for Carrying other heating items

Heat packs/hand warmers: They can be carried around, but the quantity must be sufficient for personal use. The lithium battery of the rechargeable hand warmer should be ≤100Wh.

Heating clothing: The battery should be removed and carried with you. The rest can be checked in.

Self-heating food: Prohibited from being carried or checked in as the heating packs are prone to explosion.

Iii. Travel Tips

Confirm in advance: Different airlines may have additional regulations. It is recommended to contact customer service for consultation before departure.

Safety labels: Electronic products must indicate information such as power and composition; otherwise, they may be rejected.

Alternative option: If you are concerned about shipping delays, you may consider purchasing compliant heating products upon arrival.

While keeping warm during winter travel is important, abiding by civil aviation regulations can ensure a smooth journey even more. Plan your luggage reasonably and let warmth and safety go hand in hand!
