According to the cabin baggage guidelines set by the Airline Operators Committee, cabin baggage carried onboard an aircraft must not exceed 56cm x 36cm x 23 cm (22” x 14” x 9”).
To ensure your cabin baggage meets the guidelines, you can use one of the many measuring gauges found at each check-in aisle in the Check-in Hall and at the Immigration Hall entrances of Departures Level. Please contact your airline should you need any assistance.
