well, i will offer some advise. myself and family members have had lots of HSBC point before and the best way to redeem them is to get $400 of your flight ticket for $24,000 points, so i would not advise to sell them for 1 cent per point. it is annoying to make the redemption, as you have to go through their special travel agency, but doable.
you can use multiple of these to cover the cost of expansive tickets. for instance, i made a redemption for a family member couple of years back that needed to fly to israel for emergency. the ticket cost $2000, but used $120K HSBC points...
