Every time I ring up SIA I cannot understand the lady, her accent is to strong, just want to find out how many points I need to fly from Melb return to New York business with my wife, I currently have 180,000 points, also don't understand what the letters mean. J, K? I probably am fairly dumb, but i have been obsessed with collecting points for the last 12 months and just want to know how to use the bloody things, the calculator is no help either!!
