Understanding Singapore Airlines Baggage Policy is key to stress-free travel. The airline offers free cabin baggage plus checked baggage that varies by ticket type. Travelers in Economy can check up to 30kg, while Premium and Business Class passengers enjoy up to 40kg or more. Cabin baggage is limited to 7kg per item, with size restrictions. The policy also includes rules for excess baggage, special items, and infant allowances. Online tools let you calculate extra baggage fees in advance. Always review the Singapore Airlines baggage policy online to stay informed about the most current allowances and avoid any additional charges.
