Its all quite clear on the website what a nominee is, a nominee is someone you can redeem a ticket FOR. you may use your miles to give that person a 'free' ticket. Your 20,000 miles is more than enough for a return trip booked online from Singapore to Bali or even a business class ticket one way from Bangkok to Denpasar via SIN for example. So perhaps you know someone who might benefit from a trip like that you could gift your points too by nominating them as a redemption nominee on your account,.
