Singapore Airlines cabin baggage: check total dimensions and the extra item

Each piece must have total dimensions no greater than 115 cm. That is the sum of length, width and height, not a maximum length for a single side. The additional personal item has a separate test. Singapore Airlines lists a maximum of 40 × 30 × 10 cm for the additional bag, within 80 cm total dimensions. If it exceeds that allowance, it counts toward the main cabin-baggage allowance, which can leave you needing to check one of your bags. Check the packed items rather than relying on a manufacturer’s description of a backpack as a “personal item.” A partner-operated connection can impose different cabin limits, even when the ticket was bought from Singapore Airlines.

What to do next

  1. Confirm the booked cabin and count the main cabin pieces permitted.

  2. Weigh each main bag and add its three outside measurements.

  3. Measure the extra bag against the smaller personal-item allowance and repack if it would count as a main piece.

  4. Confirm exactly which flights and excess category the purchase covers.

More booking questions

Singapore Airlines extra baggage: online eligibility comes before the price

Singapore Airlines lets eligible passengers buy additional baggage online until six hours before departure. The online option is for tickets issued by Singapore Airlines with the relevant flights operated by Singapore Airlines. A Singapore Airlines and Scoot combination on the same ticket needs a different contact route; other mixed-airline journeys may require the extra baggage purchase at the airport. The type of purchase depends on the baggage system for the itinerary. Weight-system journeys sell extra weight in increments, while piece-system travel uses additional pieces and may have separate overweight or oversize charges. An extra-weight purchase still does not allow a single bag above 32 kg. The airline also distinguishes purchases more than 48 hours before departure from later purchases, so compare the current quote for your timing rather than assuming one online discount always applies. Confirm exactly which flights and excess category the purchase covers.

Singapore Airlines missing baggage: report to the airline operating the last flight

Use Singapore Airlines’ delayed-baggage process when the final flight to your destination was operated by Singapore Airlines. If another airline operated that last flight, Singapore directs you to report to that operating airline instead. For the Singapore Airlines process, report online or at the arrival Lost & Found Office and keep the ten-character file reference. The baggage portal provides follow-up, and Singapore Airlines describes email updates for up to seven days. If the bag remains unlocated after seven days, contact the local Lost & Found Office for the baggage claim form. Prepare an accurate contents list, purchase evidence and receipts for expenses you intend to claim; the form is not a fixed compensation award. An item left onboard or in a lounge is different from a checked suitcase that failed to arrive. For items left on an aircraft arriving in Singapore or in a Changi lounge, the published route is SATS Lost & Found.
