For luggage in excess of the allowed weight, you may choose to either pay an excess baggage fee or airfreight it to your destination as unaccompanied luggage.
Do remember to check in any liquids, aerosols or gels which are in containers larger than 100ml. For more information, check general Baggage Restrictions here or with your airlines.
