Swiss Air typically permits one carry-on bag per passenger in addition to a personal item. The carry-on bag's dimensions should generally not exceed 55 x 40 x 23 centimeters (22 x 16 x 9 inches), including handles, pockets, and wheels. This size limit ensures that the carry-on bag can be safely stowed in the overhead bin or under the seat in front of you. Additionally, passengers are usually allowed to bring a personal item such as a purse, laptop bag, or small backpack. Adhering to Swiss Air's carry-on size guidelines helps passengers avoid any issues during boarding and ensures a smoother travel experience. https://baggagebee.com/blog/swiss-airlines-baggage-allowance/
