常见问题解答 (FAQ)
Frequently asked questions
Can I carry food on a plane?
Yes, solid food passes airport security without limits. Liquids, gels, and spreadable foods (yogurt, peanut butter, hummus) follow the 3.4 oz (100 ml) rule. On international arrivals, declare food to customs.
How much liquid can I carry on a plane?
Containers of 3.4 oz (100 ml) or less, all fitting in one quart-size (≈1 L) clear bag, per passenger. Medically necessary liquids and baby food are exempt.
What is the difference between carry-on and checked rules?
Security agencies decide what may pass the checkpoint into the cabin, and what may fly in the hold. Fire-risk items like lithium batteries and vapes are carry-on-only; sharp items and large liquids are checked-only.
Who has the final say on what I can bring?
The screening officer at the checkpoint, always. Even permitted items can be refused if they trigger alarms or appear tampered with.
