Singapore Airlines Baggage Policy some of the most generous allowances in the industry, primarily structured on a weight-based system that benefits all travelers. The free checked baggage allowance is determined by your cabin class, with First Class and Suites passengers enjoying the highest allowance of 50kg (110lbs), followed by Business Class at a generous 40kg (88lbs), Premium Economy at 35kg (77lbs), and a very competitive 30kg (66lbs) for all Economy Class fare types (Lite, Standard, Flexi). It's essential to note that all checked bags must not exceed 158cm (62in) in total linear dimensions (length + width + height), and bags weighing over 32kg (70lbs) are generally not accepted for manual handling safety. While this generous allowance covers most needs, should you require extra weight, pre-purchasing it online during check-in or via the "Manage My Booking" section is significantly cheaper than paying at the airport counter. For carry-on luggage, the policy is consistent across all cabins, permitting one standard cabin bag (max 55x40x23cm) for the overhead locker and one personal item (max 40x30x15cm) that fits under the seat; strict IATA liquid rules apply, and gate checks are possible if overhead space is insufficient. To ensure a smooth journey, always verify your specific route's allowance on your booking confirmation, as regional flights within Southeast Asia may have different limits, and pack essential items like medications, important documents, and valuables in your carry-on to avoid any risk of loss or delay.
