SWISS cabin baggage

You are flying with Swiss International Airlines from Zurich, Geneva, or Brussels, and you're looking for the exact rules for your carry-on baggage. The Swiss airline, a member of Star Alliance and the Lufthansa Group, applies very precise maximum dimensions for both the suitcase and personal item (handbag, backpack, or laptop). This guide centralizes all Swiss cabin baggage format rules for 2026: 55x40x23 cm gauge, 8 kg weight limit, allowance per class (Economy, Business Class, First Class), 100 ml liquids regulation, restrictions on medications, Miles & More, overhead compartment and under-the-seat checks.

Swiss Carry-on Baggage Maximum Dimensions: 55x40x23 Gauge

Swiss carry-on baggage measures a maximum of 55x40x23 cm, including wheels and handle. This standard exactly matches the IATA maximum dimensions and the gauges used by most European Star Alliance member airlines. The Swiss cabin format applies to all flights operated by Swiss International Airlines, its partners Edelweiss Air, and codeshare flights with Lufthansa, Iberia, or Air France.

What are the maximum dimensions and weight for Swiss carry-on baggage?

A carry-on suitcase on Swiss must respect 55x40x23 cm and a maximum of 8 kg, dimensions including wheels. The control gauge used at Zurich Kloten and Geneva Cointrin is strictly aligned with this standard: if the suitcase doesn't fit, it goes into the hold. Frequent long-haul travelers know that a 50 cm rigid suitcase offers a 5 cm safety margin.

How to check the gauge before departure

Before any travel, measure the suitcase flat, then add the thickness of the wheels and handle to get the actual dimension. Checking at home avoids an unpleasant surprise at the airport. To compare the standards applied by other European airlines, consult our Air France carry-on baggage guide, whose allowance is more generous at 12 kg.

Suitcase models compatible with Swiss cabin format

• Rigid 4 silent wheels suitcase, 55x40x20 cm format for a 5 cm margin
• Soft suitcase expandable up to 55x40x23 cm once compressed
• Foldable garment bag (clothing cover) if the trip is less than 5 days

Swiss Cabin Weight Limit of 8 kg: How to Avoid Excess

The Swiss cabin weight limit is a maximum of 8 kg per carry-on bag, including checks at the check-in counter and at the boarding gate. This 8 kg limit places Swiss International Airlines among the strictest airlines in Europe: Air France allows 12 kg, Lufthansa 8 kg like Swiss, Iberia 10 kg. The penalty for overweight involves checking the suitcase into the hold, with additional check-in fees often calculated in CHF (between 70 and 110 CHF depending on the destination). On transatlantic connections operated by Star Alliance partners, also compare with the Air Canada carry-on baggage rules, which apply a similar format but a different weight tolerance.

Weigh the suitcase before leaving home

To avoid excess fees, weigh the suitcase at home with a compact luggage scale (from 12 CHF). Star Alliance airlines systematically weigh the baggage of Swiss Economy class passengers since 2024. On a medium-haul flight like Zurich to Paris, checks are less frequent, but on a long-haul flight from Zurich, weighing is almost systematic.

Tips for staying under 8 kg with a Swiss carry-on bag

• Wear heavy clothing (coat, hiking boots)
• Store laptops and tablets in your personal backpack
• Carry medications and toiletries in the cabin bag under the front seat
• Prefer a lightweight carry-on suitcase, ideally less than 2.5 kg empty
• Compress clothes with packing cubes or a vacuum-seal bag

How much does overweight cabin baggage cost on Swiss?

If the suitcase exceeds 8 kg, it is tagged and sent to the hold. The fee charged varies depending on the flight ticket and destination: 70 to 110 CHF for a short-haul European flight, up to 200 CHF for a long-haul flight to the United States or Asia. The traveler can pay via the Swiss app or at the counter with a boarding pass.

Additional Small Item: Handbag, Backpack, or Laptop

Swiss International Airlines allows one small personal item in addition to the carry-on suitcase, free of charge. This handbag, backpack, laptop, satchel, briefcase, or kit must respect the format 40x30x10 cm and fit under the seat in front. Personal items such as a folding umbrella, crutches, or a light camera do not count towards the allowance. This tolerance aligns with the practices of Lufthansa, Edelweiss Air, and most Star Alliance airlines, unlike low-cost carriers.

Am I allowed a small item or handbag in addition to my carry-on suitcase?

Yes, every Swiss passenger can keep one small personal item in addition to the carry-on bag: a handbag, backpack, laptop, laptop bag, or briefcase. This plastic or fabric bag must measure a maximum of 40x30x10 cm and fit under the seat in front. However, a garment bag or clothing cover counts as a carry-on bag.

What to put in your handbag or personal backpack

• Laptop, tablet, power bank (lithium powerbank)
• Medications with prescription, glasses, medical items
• Documents: passport, flight ticket, boarding pass, baggage tag
• Small dry foods and an empty bottle to fill after security check
• Toiletries in bottles of 100 ml maximum

What does not count as a personal item

Duty-free purchases made after the security check do not count as additional carry-on baggage, provided the sealed plastic bag is kept closed until the final destination. Compact musical instruments (violin, flute) are tolerated in addition if the case does not exceed 55x40x23 cm. Folding strollers and car seats for infants travel free of charge in the hold, outside of the cabin allowance.

Allowance by Class: Economy, Business Class, Swiss First Class

The Swiss carry-on baggage allowance varies according to the travel class of the airline ticket. Swiss Economy passengers may carry one carry-on bag of 8 kg plus one personal item. In Business Class and First Class, the allowance doubles to two carry-on bags of 8 kg each, totaling 16 kg in the cabin without checking baggage. Star Alliance Gold and Senator Miles & More statuses benefit from the same rights as Business Class, regardless of the ticket price.

How many carry-on bags are allowed in Business or First Class?

In Swiss Business Class and First Class, each passenger is allowed two carry-on bags of a maximum of 8 kg each, plus one small personal item. This doubled allowance allows for carrying a garment bag for long business trips, in addition to the classic suitcase. The Swiss Economy fare remains limited to one 8 kg carry-on bag.

Baggage Advantages for Star Alliance Gold Status Holders

Travelers holding Star Alliance Gold status (Miles & More Senator, HON Circle, Lufthansa Group elite) board with the Business Class allowance even in Swiss Economy. This tolerance extends to flights operated by Star Alliance and Lufthansa Group partners: Lufthansa, Edelweiss Air, Air France (excluding codeshare), Iberia. To compare with other European airlines, see also our KLM carry-on baggage guide.

Strictness of Checks at Boarding in Zurich Kloten and Geneva Cointrin

Swiss International Airlines applies strict control of carry-on baggage at boarding, particularly at Zurich Kloten and Geneva Cointrin airports. According to user feedback on travel forums and "le routard," approximately 1 in 5 passengers is asked to place their suitcase in the gauge during long-haul flights departing from Zurich. Tolerance is lower than in Brussels or Vienna, and agents systematically weigh the carry-on baggage of school groups and Swiss Economy passengers. This rigorous regulation aligns with the Lufthansa Group policy.

Is Swiss strict about the size and weight of carry-on baggage?

Yes, Swiss Air is very strict about carry-on baggage, especially when departing from Zurich and Geneva. Ground agents check the gauge (55x40x23 cm) and weigh the suitcase if in doubt. An excess of 500 g may sometimes pass, but 1 kg of overweight systematically triggers the bag being checked into the hold, with applicable fees at the boarding gate.

How the overhead compartment check works

When boarding the plane, staff visually check the size of the suitcase. If the suitcase does not fit into the metal gauge at the boarding gate, it goes into the hold for free. A specific baggage tag is affixed, and the suitcase is collected on the belt upon arrival. Connecting travelers check their tag to ensure the suitcase reaches its final destination.

Swiss baggage dispute: what to do in case of a problem

In case of a baggage dispute (loss, delay, damage), the declaration must be made at the Swiss counter before leaving the baggage area. The passenger fills out a Property Irregularity Report (PIR) and keeps the reference number. The Swiss airline covers lost baggage according to the ICAO Montreal Convention, capped at approximately 1,600 SDRs (Special Drawing Rights), or about 2,100 CHF. For official details, consult the official Swiss International Airlines baggage guide.

Liquids Regulation in Cabin: The 100 ml Rule

The liquids regulation in Swiss cabins complies with the European IATA standard: all bottles of liquids, gels, creams, cosmetics, and semi-solid foods must contain a maximum of 100 ml each, grouped in a transparent, zippered bag of maximum 1 liter. This 100 ml rule also applies to perfumes, body lotions, and recharged electronic cigarettes. Travelers must remove this transparent bag from their carry-on before passing through security (PIF - Poste d'Inspection Filtrage). Medications with prescriptions and baby food are exceptions and are allowed in larger quantities.

What are the rules for transporting liquids in the cabin with Swiss?

Liquids of maximum 100ml must be placed in a transparent, sealed one-liter bag, presented separately at the PIF control. This IATA standard applies to all European airlines: Lufthansa, Air France, Iberia, Edelweiss Air, Swiss International Airlines. Duty-free purchases made after control are still permitted in larger quantities, in their original sealed plastic bag.

Detailed list of liquids subject to the 100 ml rule

• Liquid cosmetics: perfume, lotion, sunscreen, makeup remover
• Toiletries: shampoo, shower gel, toothpaste, gel deodorant
• Semi-solid foods: yogurt, honey, jam, cream cheese, soup
• Non-prescription liquid medications (syrup, eye drops)
• Electronic cigarette refill liquid (vape)

Exceptions to the 100ml liquids rule

Prescribed medications with a medical prescription in French, German, or English are exempt from the 100 ml limit. Passengers travel with their prescription and declare it at the PIF. Baby foods (infant formula, baby jars, water for preparation) are allowed in reasonable quantities for the duration of the flight. Travelers with pets (dog, cat) may carry water in appropriate quantities.

Prohibited Items in Swiss Carry-on Baggage: The List to Know

Swiss International Airlines applies the IATA list of items strictly prohibited in the cabin. Weapons, ammunition, explosives, flammable chemicals, non-compliant lighters, screwdrivers, and tools larger than 6 cm are prohibited in carry-on baggage and will be confiscated at the PIF without refund. Some items are tolerated in checked baggage but not in the cabin: knives of all sizes, sharp scissors, open razors, and lithium power banks exceeding 100 Wh. Travelers should check their toiletry bag before check-in to avoid confiscations.

What items are strictly prohibited in carry-on baggage?

Items prohibited in Swiss cabin baggage include weapons, ammunition, explosives, non-aviation lighters, screwdrivers over 6 cm, sharp scissors, knives, and blade razors.
