Can you bring a laptop on a plane? Check its battery and fare

A laptop can normally travel with you, provided its battery and the airline’s conditions permit it. Cabin carriage is preferred. This is not a promise for every model, route or quantity of devices.

Before packing

Read the battery’s watt-hour rating. Under the FAA US guidance, lithium-ion batteries up to 100 Wh use the ordinary passenger category; larger batteries through 160 Wh need airline approval, and above 160 Wh exceeds the passenger allowance. Airline and route restrictions can be stricter. Check the actual specification rather than assuming a capacity from the laptop’s brand or screen size.

A laptop bag counts within your purchased bag allowance unless the airline expressly grants an exception. Weigh the filled bag with its charger. For several devices, verify device/battery quantity limits and destination import conditions rather than treating personal-use guidance as an unlimited allowance.

Cabin or hold?

An eligible device with an installed battery may be checked under FAA conditions only if completely switched off and protected against damage and accidental activation. Sleep and hibernation do not count. Confirm the airline’s policy; keeping your laptop with you is preferable.

Spare lithium batteries and power banks must stay in the cabin. Remove them before a gate check and protect their terminals against short circuits. Their capacity, quantity, storage and onboard use can have stricter airline conditions. Do not fly with a dangerous damaged or recalled battery unless the applicable removal or safety conditions are satisfied.

At security and on board

Standard TSA screening uses a separate laptop bin; PreCheck permits the laptop in the bag. Follow the actual checkpoint. The UK guide requires a device to turn on if requested, so leave enough charge for that check.

Follow crew instructions for stowing the laptop. Use airplane mode or turn cellular transmission off; onboard Wi-Fi requires equipment and airline permission. Do not assume sockets or permission to charge from a power bank.

For the wider explanation, read laptop batteries and screening. Use the bag checker for bag dimensions; it cannot authorize batteries.
