Every flight begins not with boarding, but with luggage. The color, brand, and even price no longer matter – dimensions, weight, and contents are important. Airlines set norms, violation of which results in additional expenses for carrying items in the cabin. Therefore, understanding what can be taken in carry-on luggage on the plane helps avoid unexpected charges, delays, and confiscations during inspection.
Size and weight of carry-on luggage: centimeters with millimeter precision
Airlines establish clear limits on size. For example, Aeroflot allows a bag no larger than 55×40×25 cm and weighing up to 10 kg, while Pobeda allows 36×30×27 cm and a maximum of 10 kg only in paid tariffs. Lufthansa – up to 8 kg, Turkish Airlines – up to 8 kg in economy and 16 kg in business (2 places of 8 kg each). The size of carry-on luggage should not exceed the specified limits: even a few extra centimeters become a reason for registering baggage and paying extra.

Passengers often overlook checking the dimensions of their backpack, bag, or suitcase, forgetting that a soft backpack fits within the norms, while a hard case does not. Carry-on luggage on the plane undergoes visual and actual control during check-in, inspection, and boarding. An oversized item is immediately sent to the baggage compartment for an additional fee.
What can be taken in carry-on luggage on the plane: strictly according to the list
Restrictions are based on safety considerations, but some rules are related to tariffs, airline policies, and control conditions. The full list is approved by ICAO and specified by each airline.
In the aircraft cabin, you are allowed to carry:
- Small electronics: smartphones, laptops, headphones, power banks (up to 20,000 mAh).
- Personal documents and money: wallets, passports, tickets.
- Liquids – in containers up to 100 ml each, totaling no more than 1 liter. All bottles – in a transparent resealable bag.
- Medicines and prescription drugs, including insulin and inhalers. Preferably – with a prescription.
- Baby items: purees, formulas, bottles, diapers – without weight or quantity restrictions, but within reason.
- Valuables: jewelry, gadgets, important papers.
- Food for the flight, if it does not contain liquids or sauces.
- One umbrella, cane, laptop without a case, or camera.
- Books, magazines, travel pillows.
This list defines the basis of what can be taken in carry-on luggage on the plane without the risk of confiscation. During check-in and boarding, control service staff may additionally restrict even permitted items based on the situation.
What is not allowed in carry-on luggage: list of prohibitions
Strict rules regulate not only the size of luggage but also its contents. The main goal is to exclude potentially dangerous or unverifiable items.
Prohibited items include:
- Sharp objects (knives, scissors, manicure sets with blades).
- Gas cylinders, lighters with fuel, matches.
- Liquids in containers over 100 ml, even if only a little is left.
- Alcohol over 70% ABV.
- Self-defense items, stun guns.
- Tools, screwdrivers, construction tools.
- Food products with liquid consistency (honey, jam, pâtés, soups).
Restrictions apply to all destinations without exceptions. Airport control detects prohibited items with high precision – during inspection or boarding. Violating the requirements leads to confiscation of the item without return and, in some cases, administrative responsibility.
Control, check-in, boarding: where and how they check
Control is carried out in three stages: during baggage check-in, during inspection before entering the sterile zone, and directly before boarding. Each step checks the compliance of items with the requirements for carry-on luggage: dimensions, weight, contents.
During check-in, staff weigh and measure the suitcase or bag. If the tariff system allows only one place, any additional backpack is equated to oversized baggage. European airports often have strict guidelines, including size checks in a metal template.
During inspection, inspectors pay attention to liquids in carry-on luggage, the presence of electronics, and suspicious items. Automatic scanners scan the contents, and selective checks involve inspection and testing for explosive substances.
Checked baggage and oversized items: tariff determines the rules
Most airlines link restrictions to the chosen tariff. Budget carriers such as Ryanair, Wizz Air, Pobeda, include only basic carry-on luggage with minimal parameters in the price. Adding a backpack, second bag, or increasing dimensions requires an additional fee.
Passengers who overlook the tariff face immediate payment for oversized baggage at the check-in counter. In some cases, carry-on luggage is sent to the baggage compartment without the possibility of returning items on board. The benefit of a “cheap” ticket disappears if the rules are violated. It is important to carefully study the tariff conditions before purchasing a ticket, especially regarding weight and number of items.
What can be taken in carry-on luggage on the plane: electronics, medicines, and baby items
Different groups of items are subject to specific norms. For example, electronics must be available for inspection: laptops are taken out of the bag, power banks are marked with capacity. Devices are allowed in quantities up to two pieces. Batteries – only in the cabin, not in checked baggage.
Medicines are allowed in any quantity if needed during the flight. It is advisable to accompany packages with a prescription or a doctor’s note. Baby items, including milk formulas, are allowed without restrictions but undergo separate control. In the aircraft cabin, you can carry sterilizers, bottles, diapers, warmers.
Understanding what can be taken in the aircraft cabin eliminates conflicts during inspection and allows you to keep necessary items with you. Practice shows: a bag with medicines, gadgets, and documents should always be at hand.
How to save money: a strategic approach to packing
Violating carry-on luggage requirements leads to financial losses. Exceeding weight – a fine. Second bag – payment. Prohibited items – disposal.
To avoid losses:

- Check the weight of carry-on luggage on household scales – even a deviation of 300 grams can have an impact.
- Pack electronics and documents in a separate lightweight bag, considering the airline’s requirements.
- Move some clothing onto yourself: a jacket with pockets can hold more than allowed in the luggage.
- Use compression bags and soft backpacks.
- Study the tariff and pay for an additional space for items in the cabin in advance – online payment is cheaper than at the airport.
This strategy reduces expenses and eliminates force majeure situations during check-in and inspection. A thoughtful approach to packing minimizes the risk of overspending and avoids spontaneous expenses at the airport. Rational distribution of items ensures efficient passage through control and saves time.
What can be taken in carry-on luggage on the plane: conclusions
Baggage allowed for transport in the aircraft cabin becomes a strategic tool if approached consciously when collecting contents. Knowledge of parameters, understanding of limitations, and attention to details allow for smooth passage through control, saving money, and keeping everything necessary with you. The main thing is to clearly define what can be taken in carry-on luggage on the plane, considering requirements, rules, and flight goals.
