How baggage rules are layered
Three layers of rules, one direction of change
Every airline's baggage rules are built on the same legal baseline: the ICAO Technical Instructions and the IATA Dangerous Goods Regulations define what passengers may carry, and security screening adds rules like the 100ml liquids limit. Airlines can only tighten these rules — they can never loosen them. That is why this tool anchors its verdicts to the international baseline.
Why "not allowed" is final but "allowed" comes with a reminder
Because rules only move in one direction, the two answers carry different certainty. When the baseline forbids something — like a power bank in checked baggage — no airline anywhere can allow it, so the verdict is final. When the baseline allows something, an individual airline may still be stricter, so every "allowed" here comes with the reminder to check your airline's own notice. Items where differences are common carry an extra variance flag.
What this tool deliberately does not cover
Three things are out of scope: customs and quarantine (whether food or medicine may enter a country), airline pricing rules (bag size and weight allowances), and per-airline policies. Mixing them in would blur what can be answered with certainty. When your item touches those areas, the verdict says so and points you to the right source.
FAQ
Common questions and answers about this topic.
Can I put a power bank in checked baggage?
No. Spare lithium batteries and power banks must never go in checked baggage — this is an international rule no airline can loosen. Carry them in your carry-on: up to 100Wh needs no approval, 100–160Wh requires airline approval, and above 160Wh is not allowed at all.
How much liquid can I take through security?
Each container must hold 100ml or less, and all containers must fit in one transparent resealable 1-litre bag. Baby food, breast milk and necessary medication are exempt — declare them for separate screening. Drinks bought inside the restricted area after screening can be taken on board.
Can I bring a lighter on a plane?
The international baseline allows one lighter per person, carried on your body (for example in a pocket) — not inside your bag, and never in checked baggage. Blue-flame and cigar lighters are forbidden. Note that some routes ban lighters entirely, such as flights in mainland China, so check before you fly.
Why can't lithium batteries go in checked baggage?
A damaged or short-circuited lithium battery can ignite, and a fire in the cargo hold cannot be spotted or fought the way it can in the cabin. Keeping spare batteries in carry-on means a problem is noticed immediately and the crew can respond. That is also why terminals should be taped or kept in original packaging.
Will my duty-free alcohol survive a connecting flight?
It depends on the transfer airport, not your first airport. Keep the bottle sealed inside the tamper-evident bag (STEB) with the receipt visible; many airports accept this at transfer screening, but some do not. If your connection requires passing security again and the airport does not accept STEBs, the bottle will be confiscated — buying at the last airport or packing alcohol in checked baggage avoids this.
