Each Guest is only allowed one Carry-on luggage with a maximum weight of 7kg (15.4 lbs.), and one additional personal item (such as a handbag, camera or digital device) onboard. BOTH items combined should not exceed the dimensions of 56 x 36 x 23cm (22" x 14" x 9"). Duty-free goods purchased after check-in will need to be within the size and weight limitations of the carry-on requirements stated above. Any items exceeding weight or size restrictions will have to be checked in, and fees will apply.

Pre-screening of excess carry-on baggage will be performed at the boarding gate to prevent excessive overhead bin loading. Any excess baggage will be charged according to airport counter fees. Please arrive at the boarding gate at least 1 hour prior to departure time to prevent any delays.

Due to limited space in the overhead lockers, you may still be required to check in your approved carry-on baggage at the boarding gate without any fees. Overhead lockers will be filled on a first-come-first-served basis, you are advised to line up for boarding earlier if you have any strong concern on this.


Have a Carry-on luggage? Have a backpack? Plan ahead for more savings!
When you are bringing a 18” – 20” Carry-on luggage, possibly you won’t be able to carry another backpack as both items combined dimension are very likely to exceed the restrictions above. When you are bringing backpack plus another bag, the larger of the two will be treated as your Carry-on luggage and will be weighed accordingly. Please remember both items combined should not exceed the dimensions mentioned above. Check your bag size and weight before departing to the airport for a hassle-free journey. We recommend our Guests to pre-book necessary checked baggage allowance online to avoid any last-minute airport fees.
