If the number of items of free baggage is exceeded, there will be a charge for every additional item of baggage. SWISS does not accept any items of baggage weighing more than 32 kg and exceeding a total size (width + height + depth) of 292 cm.

Swiss International Air Lines (SWISS) is generally known for being quite strict regarding baggage weight and dimensions, adhering closely to their published policies. For carry-on luggage, Economy passengers are strictly limited to one bag weighing no more than 8 kg (18 lbs). Ground staff at busy hubs like Zurich or Geneva frequently weigh carry-on bags at the gate, especially on full flights; if your bag exceeds this limit, you may be forced to check it and pay an at-gate fee. For checked baggage, the limit is typically 23 kg (50 lbs) for Economy and 32 kg (70 lbs) for Business and First Class. While they might occasionally overlook a few hundred grams, anything more than 1 kg over the limit will usually trigger an "excess baggage" fee. SWISS does, however, offer a unique "Light" fare that excludes checked baggage entirely, so travelers must be careful to book the "Classic" or "Flex" fare if they need a suitcase. To avoid surprises, it is highly recommended to weigh your bags at home and ensure your "personal item" (like a laptop bag) fits within the 40 x 30 x 10 cm dimensions.
