Do you provide free check in baggage allowance?

No. If you travel with check in baggage you will be charged a fee at different rates depending on the airport from which you fly. You may access our fee schedule here. Do be aware that you will be charged a flat rate for the first 15kg and a different rate for each additional kg at the airport.

You can however save on baggage charges by pre-booking baggage online at airasia.com during the booking process or via Manage My Booking. A minimum of 15kg of checked baggage may be purchased at first instance and you can UPSIZE at the incremental weight of 5kg or SUPERSIZE it to 30kg. If you UPSIZE or SUPERSIZE your baggage four hours or more before scheduled departure, you can save up to 50% on charges.

If your actual baggage weight is less than the pre-booked weight, fees paid are non-refundable. However, baggage weight is transferable from one guest to another, if they are travelling on the same itinerary.
