Can You Bring a Laptop on a Plane? Yes — Carry-On

Yes, you can bring a laptop on a plane. Laptops are permitted in carry-on baggage on all major airlines worldwide, and carry-on is strongly recommended over checked baggage. Here is everything you need to know before you fly.

Carry-On: The Right Place for Your Laptop

Every major airline and aviation authority — including the TSA, EASA, and the UK CAA — permits laptops in carry-on bags. There is no restriction on brand, size, or model. MacBooks, Windows laptops, Surface devices, ThinkPads, gaming laptops, and ultrabooks are all fine.

Put your laptop in your carry-on. Not your checked bag. The reasons are straightforward:

Theft. Laptops are among the most frequently stolen items from checked baggage. Once your bag leaves your hands at the check-in desk, you have no visibility over who handles it.

Physical damage. Checked bags are dropped, stacked under heavy loads, and experience more vibration than carry-on bags stored in an overhead bin. Even a well-padded laptop bag provides less protection in the cargo hold than in the bin above your seat.

Temperature. Cargo holds on some aircraft can experience temperature extremes during long-haul flights, which is not ideal for electronics and lithium batteries.

Security Screening: Removing Your Laptop

This is where most travelers run into confusion. At US airports (TSA) and UK airports, the rule is clear: you must remove your laptop from your bag and place it in a separate bin on the X-ray belt. It cannot stay inside a sleeve or bag during screening.

CT scanners are gradually being deployed at more airports, and these advanced machines can see inside bags well enough that removal is not required. Some US airports and major European hubs are moving toward CT screening. However, the safest assumption unless you see a sign at the checkpoint is that you will need to remove your laptop.

Practical tip: pack your laptop in the top-most or most accessible section of your carry-on. Having to unpack half your bag at security is stressful when there is a queue behind you.

Battery Limits: Are You Within the Rules?

Laptops contain lithium-ion batteries, and aviation authorities regulate lithium batteries by their watt-hour (Wh) capacity.

The key number is 100 Wh. Batteries under 100 Wh are permitted in carry-on without any special approval. The vast majority of laptop batteries fall within this range:

• MacBook Air (M2): approximately 52 Wh
• MacBook Pro 14-inch: approximately 70 Wh
• MacBook Pro 16-inch: approximately 100 Wh (right at the limit — technically allowed)
• Dell XPS 13: approximately 55 Wh
• ThinkPad X1 Carbon: approximately 57 Wh

Gaming laptops with large batteries occasionally approach or exceed 100 Wh. If you are uncertain about your battery capacity, check the manufacturer's spec sheet or look for a label on the battery itself (accessible by removing the back panel on older models). Batteries between 100 Wh and 160 Wh can fly with airline approval — contact your airline before the trip.

Checked baggage and lithium batteries: technically, a laptop with its battery installed can go in checked baggage. But many airlines have begun restricting loose or spare lithium batteries in checked bags entirely, and some restrict installed batteries in powered-off devices as well. Do not put your laptop in checked luggage.

Multiple Laptops: Allowed

Business travelers and digital nomads often carry two laptops. There is no official per-passenger limit on the number of laptops you can bring in carry-on. TSA and equivalent agencies in the UK and EU impose no restriction on quantity — each device will simply need to be screened (and removed from the bag) individually.

Some travelers ask about carrying two laptops at customs. For personal use, two laptops rarely raise issues. If you are entering with multiple brand-new laptops, customs officers may occasionally ask about commercial intent.

Budget Airlines and Laptop Allowances

On full-service airlines, a laptop in a bag or sleeve typically does not affect your carry-on allowance in any meaningful way. On budget airlines, the situation is different.

Ryanair, EasyJet, Wizz Air, and similar carriers impose a strict personal item or "small bag" allowance. If your laptop is in a separate sleeve or backpack rather than inside your main cabin bag, it may count against your personal item allocation. Check your airline's specific policy before packing.

Practical Tips

• Use a dedicated laptop sleeve or padded compartment rather than leaving the laptop loose — it protects the screen and makes security removal faster
• Label your laptop with your name and email address on a small sticker inside the lid — useful if it goes through security separately and gets left behind
• Keep your charger accessible on long-haul flights; USB-C power banks (under 100 Wh) can top up your battery if the seat has no outlet
• Check your battery Wh if you own a gaming laptop with a large battery before you fly
• Do not pack your laptop in a bag you check at the gate — gate-checked bags go in the hold and you lose the theft and damage protection of carry-on

What About Airline-Specific Rules?

Most airlines do not have special laptop rules beyond the standard carry-on and battery limits. If you are flying on an airline you are unfamiliar with, verify:

1. Whether a personal item is included in your ticket (budget airlines often charge extra)
2. Whether your laptop bag counts as your personal item or your main cabin bag
3. Whether any per-device battery limits apply (rare, but occasionally seen on charter operators)
