Baggage fees
No reliable fixed price is listed here. Check your booking for the cost of adding a bag; an unlisted price does not mean it is free.
Official baggage policyHow to use this policy
Check cabin bag dimensions, weight and personal-item limits separately. A bag has to pass every published limit at once; being under the length and width limit does not help if the depth, weight, or fare-specific allowance is tighter.
Editorial signal only. Measure the packed bag and verify the operating carrier's rule.
Swiss International Air Lines liquids policy
Check every departure and transfer checkpoint. At most airports: containers up to 100 ml in one transparent resealable 1-litre bag. Zurich's main security checkpoint for journeys starting there permits containers up to 2 litres; its transfer checkpoints and SWISS First Lounge A are excluded. Double-walled containers must be empty. Medicine and baby-food exceptions have conditions.
Family & Infants
Infant (under 2)
An infant on an adult's lap has no cabin-bag allowance. Infant checked baggage depends on the fare: European Comfort, Comfort Green and Flex include one bag up to 23 kg; intercontinental fares include one up to 23 kg except Light fares. Check the infant's ticket separately.
Stroller
Small children have a foldable pushchair or fully foldable travel-pram allowance on all fares. Register it at check-in; use up to the aircraft and return location depend on the airport. A pocket buggy carried in the cabin must fit within the cabin allowance.
Car seat
For cabin use, book the child a separate seat and confirm the restraint is certified for air travel, with base dimensions no larger than 40×40 cm. SWISS lists a baby carry cot OR child seat per infant as an additional permitted item for adults and children with their own seat. Free hold carriage of any car-seat model is not established by the reviewed sources.
