Swiss International Air Lines (Swiss Air) typically allows Economy class passengers one piece of cabin baggage with dimensions not exceeding 55 x 40 x 23 centimeters. Business and First class passengers may enjoy a more generous allowance. Additionally, passengers are often allowed a personal item like a handbag or laptop bag. The weight limit for cabin baggage is generally in the range of 8-12 kilograms, but it's advisable to check Swiss Air's official website or contact the airline directly for the most accurate and up-to-date information, as policies can change over time.
