Never put power banks or spare lithium batteries in checked luggage — they are cabin-only by aviation safety rules. Also keep cash, jewellery, laptops, phones, passports, essential medicines, keys, fragile items and important documents with you in the cabin. Checked bags can be lost, delayed or opened, and airline liability for a lost bag is capped, so anything valuable or irreplaceable should never leave your hands.

Packing feels like a game of Tetris — but where an item goes matters more than most travellers think. Some things belong in the cabin with you, full stop. A few of them aren’t just “better in your hand bag” — they’re banned from the hold for safety reasons, and a security officer can pull your bag off the belt because of them.
Here’s the short version: if it’s dangerous, valuable, irreplaceable, or you’d be stuck without it — carry it on. This guide walks through exactly what should never go in checked luggage on Indian flights in 2026, and the real reasons behind each rule.
What should you never put in checked luggage?
Never check power banks or spare lithium batteries — they must travel in the cabin under DGCA and international aviation safety rules, because a battery fire in the sealed cargo hold can’t be reached or fought in flight. Beyond that safety rule, keep anything you can’t afford to lose in your cabin bag: cash, jewellery, gadgets, your passport, essential medicines, keys and important papers.
The logic splits into two buckets. One is safety — items that are simply not allowed in the hold. The other is risk — items that are allowed down there but shouldn’t be, because checked bags get delayed, misrouted, occasionally opened for inspection, and airline payouts for loss are limited. Let’s take them in order.
Power banks and spare lithium batteries
This is the one hard, non-negotiable rule: power banks and loose lithium batteries go in the cabin, never in checked luggage. Lithium cells can overheat or short-circuit, and in the pressurised cargo hold there’s no one to catch a fire early. Keeping them in the cabin means any problem is spotted and dealt with in seconds.
A few practical points that trip people up. Spare batteries should have their terminals taped or sit in a case so they can’t short against coins or keys. Watt-hour and quantity limits apply and vary — a very high-capacity power bank may be restricted or need airline approval, so confirm the current figure with your airline before you fly. And yes, this covers the power bank buried in the bag you were about to check.
We go deeper on capacity limits and airline-by-airline specifics in our power bank rules for Indian flights guide.
Other items with a safety angle
Lithium isn’t the only category the hold treats differently. Spare batteries of most kinds are happier in the cabin. Anything flammable, pressurised or clearly hazardous is restricted everywhere — that’s standard. On the flip side, liquids over 100ml belong in your checked bag, because the 100ml cabin limit is a security rule, not a cargo one. When in doubt about a specific gadget, e-cigarette or oddity, check the airline’s dangerous-goods list rather than guessing.
Why is checked luggage risky for valuables?
Because you lose sight of the bag the moment it leaves the counter, and if it’s lost or delayed, airline compensation is capped — not “whatever was inside”. Checked bags travel through belts, tugs, sorting systems and sometimes a second aircraft on connections. Most arrive fine. But when one doesn’t, you’re relying on a liability limit, not the actual value of your gold or your laptop.
That gap is the whole point. A misrouted bag on a connection, a delayed transfer, or a bag that simply doesn’t show up on the belt are ordinary travel events — not rare disasters. The fix isn’t to panic; it’s to make sure the bag that goes missing never contained anything you truly can’t replace.
Cash, jewellery and gold
Cash and jewellery should never see the inside of a checked bag. There’s no realistic way to prove how much cash was in a lost suitcase, and valuables are exactly what gets targeted if a bag is tampered with. Wear or hand-carry your jewellery, and keep cash on you. If you’re carrying significant gold or jewellery, there are separate carriage and customs considerations — our guide on how much jewellery you can carry on domestic flights covers the etiquette and the paperwork.
Electronics: laptop, phone, camera
Laptops, phones, tablets, cameras and headphones belong with you. They’re valuable, fragile and easily “lost” — and many of them contain lithium batteries anyway, which nudges them toward the cabin on safety grounds too. A checked laptop can arrive with a cracked screen from a rough transfer, and that’s rarely covered the way you’d hope. Slip devices into your personal item or cabin bag and keep them close.
Passports, documents and keys
Your passport, visa, ID, tickets, house and car keys, and any important documents must stay on your person or in your cabin bag. Imagine landing and realising your passport flew off to a different city inside a delayed suitcase — at immigration, that’s a genuine problem, not an inconvenience. Keys are just as bad: a delayed bag can leave you locked out of your own home. Keep a photo or scan of key documents on your phone as backup.
Where should medicines and prescriptions go?
Essential medicines belong in your cabin bag, along with a copy of the prescription — never checked, and never split from you. If your bag is delayed even a day, a checked-away medication you need on schedule becomes an emergency in an unfamiliar city. Carrying it in the cabin means it’s with you the whole journey, delays and diversions included.
A few sensible habits make this painless. Carry a little more than the trip length in case of delays. Keep medicines in original labelled packaging, and pack a copy of the prescription or a doctor’s note — useful at security and, for some medicines, at customs. For anything requiring a syringe, or for larger liquid medicines that exceed the usual cabin liquid limit, tell the security officer up front; genuine medical items are handled sensibly.

What does airline liability actually cover if a checked bag is lost?
Airline liability for a lost, damaged or delayed checked bag is capped by international rules — not by what your bag was worth. On international journeys, the Montreal Convention sets a per-passenger limit for baggage; on domestic Indian flights, DGCA-linked rules apply. Either way, the cap is often well below the value of jewellery, gadgets or cash, which is precisely why those items should never be checked.
Two things follow from this. First, the exact liability figures change and are expressed in special units for international travel — so confirm the current amounts with your airline or the relevant authority rather than relying on a number you half-remember. Second, valuables generally aren’t covered up to their real value even within the cap. If the contents matter, the answer isn’t a bigger claim later — it’s keeping them in the cabin now.
| Item | Cabin or checked? | Main reason |
|---|---|---|
| Power bank, spare lithium batteries | Cabin only | Safety — fire risk in the hold (mandatory) |
| Cash, jewellery, gold | Cabin | Theft and loss; liability is capped |
| Laptop, phone, camera | Cabin | Valuable, fragile, often has a battery |
| Passport, documents, keys | Cabin | Irreplaceable; delayed bag strands you |
| Essential medicines + prescription | Cabin | You need them on schedule if bag is delayed |
| Fragile items (glass, gifts, souvenirs) | Cabin | Rough handling in the hold breaks things |
| Liquids over 100ml | Checked | 100ml cabin limit is a security rule |
Capacity limits, liability figures and airline policies vary and change — verify the current details with your airline before you travel.
What about fragile items and gifts?
Fragile things — glassware, framed photos, wedding gifts, delicate souvenirs — do far better in the cabin, where they aren’t dropped from a belt or crushed under other bags. Checked luggage is handled roughly by design; it’s thrown, stacked and jolted. If something would shatter under a heavy suitcase, it shouldn’t be in the hold.
When cabin space genuinely won’t allow it, wrap the item deep inside soft clothing, keep it centred away from the bag’s edges, and accept the risk knowingly. For anything precious, though, the honest answer is to carry it on or ship it separately. A “fragile” tag helps at the margins, but it isn’t a force field.
How do you pack so nothing important ends up in the hold?
Build a small “never-check” kit and pack it first, into the bag that stays with you. The habit beats memory every time — decide once, then repeat it every trip. A quick pre-airport sweep of your checked bag for stray power banks and valuables takes thirty seconds and saves a belt-side scramble.
A simple routine that works:
- Cabin bag, always: power bank and batteries, phone, laptop, passport and documents, wallet and cash, jewellery, essential medicines with prescription, keys, and one change of clothes in case the checked bag is delayed.
- Checked bag: clothes, shoes, toiletries, liquids over 100ml, and anything bulky you could replace without heartbreak.
- Final check: before you hand over the checked bag, confirm no power bank, charger with a built-in battery, or valuable slipped in.
Doing web check-in before you reach the airport also gives you a calmer moment to sort cabin-versus-checked at home rather than in a queue. And if you’re weighing what your airline actually allows in each bag, check the baggage allowance details for your carrier first.
Common Questions
Can I put a power bank in checked luggage if it’s switched off?
No. Power banks and spare lithium batteries must always travel in the cabin, switched off or not — it’s a safety rule, not a convenience preference. The risk is a battery fault in the sealed hold where no one can respond. Keep them in your cabin bag, with terminals protected, and confirm capacity limits with your airline.
Is it illegal to check jewellery or cash?
It’s usually not illegal, but it’s a bad idea. If the bag is lost, delayed or opened, airline liability is capped and there’s no practical way to prove what cash was inside. Valuables are also the first target of tampering. Carry cash on you and wear or hand-carry jewellery. For significant gold, also check the relevant carriage and customs rules.
Where should I keep medicines I take daily?
In your cabin bag, with a copy of the prescription. If a checked bag is delayed even a day, a medication you need on schedule can become an emergency. Keep medicines in original labelled packaging, carry slightly more than the trip length, and tell security about anything unusual like syringes or larger liquid medicines.
How much will the airline pay if my checked bag is lost?
Compensation is capped by international rules (Montreal Convention on international routes) or DGCA-linked rules domestically — not by what the bag was worth. The cap is often below the value of gadgets, jewellery or cash. Figures change and use special units internationally, so confirm the current amount with your airline or the authority, and keep valuables in the cabin.
Can I check liquids over 100ml?
Yes — larger liquids belong in your checked bag, because the 100ml limit applies only to cabin baggage as a security measure. So full-size toiletries, perfumes and similar go in the hold. Just keep essential liquid medicines with you in the cabin and flag them at security if they exceed the usual cabin liquid limit.
What’s the single most important thing to never check?
Power banks and spare lithium batteries — that’s the one true “never” for safety reasons, enforced everywhere. After that, treat passports and essential medicines as non-negotiable cabin items, since losing them mid-journey causes real problems. Everything else valuable follows the same logic: if you can’t replace it or can’t be without it, carry it on.
