Carry-on luggage: items that some airlines no longer allow

He hand luggage It is undergoing the most profound regulatory transformation of the last decade, as multiple international airlines have begun to ban certain common technological items and travel accessories this year.

These modifications aim to streamline inspection processes at airports and, above all, ensure passenger safety in the face of the increase in incidents related to faulty batteries and overloads in aircraft cabins.

What items are prohibited in cabin baggage?

The main concern of aviation safety committees lies in devices containing high-capacity lithium-ion batteries without certified thermal management systems.

For this reason, smart luggage with integrated, non-removable batteries has been definitively banned by the vast majority of airlines worldwide.

If security inspectors detect that the energy accumulator is sealed inside the physical structure of the suitcase, they will not allow it into the boarding area under any circumstances.

Similarly, certain types of plasma lighters, large portable solar chargers, and foldable electric scooters have been completely excluded from what a passenger can carry in their luggage. hand luggage.

Why do airlines constantly change their safety regulations?

The introduction of three-dimensional computed tomography (CT) scanners in the most modern airports has made it possible to accurately identify the chemical composition of transported objects without having to remove them from the suitcase.

This technological advance has revealed that many inexpensive, generic electronic devices present a high risk of short circuit and subsequent thermal runaway within the overhead compartments of the aircraft.

Furthermore, the increase in air traffic and the need to reduce aircraft turnaround times on runways are putting pressure on airlines to standardize and limit the volume of luggage allowed in the cabin.

To consult the official regulations on the transport of dangerous goods and the authorized technical specifications, travelers can visit the official portal of the International Air Transport Association (IATA).

These international regulations aim to mitigate the risks of catastrophic fires at high altitude, ensuring that flight personnel can quickly control any thermal anomalies in passenger devices.

What are the standard size and weight limits allowed for travel?

Each airline sets its own weight and size limits for cabin baggage based on the aircraft model and the travel fare selected by the customer.

Exceeding these physical dimensions usually entails paying high financial penalties directly at the boarding gate, in addition to the obligation to check the suitcase in the cargo hold of the plane.

Below is a detailed comparative table showing the maximum dimensions and weight restrictions applied by some of the leading airlines in the market this year:

International Airline	Maximum Measurements (cm)	Maximum Weight Allowed	Key Device Restriction
Iberia	56 x 40 x 25 cm	10 kg	Removable lithium batteries are mandatory
Ryanair	40 x 20 x 25 cm	It should fit under the seat	Extra charges for standard cabin baggage
American Airlines	56 x 36 x 23 cm	No weight limit	Suitcases with integrated batteries are prohibited.
Lufthansa	55 x 40 x 23 cm	8 kg	Power banks limited to 100 Wh capacity

This information demonstrates the importance of verifying specific requirements before arriving at the airport, thus avoiding unforeseen delays and unnecessary additional charges during the check-in process. hand luggage.

How does airport security technology influence restrictions?

The deployment of new airport security systems is progressively redefining the classic rule of liquids allowed on short and long-haul flights.

At airports that have already implemented the advanced, state-of-the-art CT scanners, passengers can carry standard-sized liquid bottles without the historical limitation of one hundred milliliters.

However, since this technology has not been uniformly installed in all airports worldwide, travelers should still take the precaution of complying with traditional regulations to avoid confiscations at intermediate stops.

How to pack your cabin bag efficiently and safely?

Planning the distribution of items within your cabin luggage greatly facilitates passing through security checks and reduces the possibility of material damage to your belongings.

Always place larger electronic devices, such as laptops and tablets, at the top or in easily accessible outer pockets for quick and easy removal.

Similarly, keep prescribed medications along with their corresponding medical reports in a separate toiletry bag to present them immediately upon request from airport health authorities.

To access lists of items prohibited for national security reasons and detailed customs regulations, users can consult the updated guidelines of the Transportation Security Administration (TSA).

Travel with peace of mind in the age of modern aviation

The key to avoiding problems before boarding the plane lies in staying informed about the constant operational and regulatory changes implemented by international airlines.
