Singapore Airlines (one of my recommended programs) has prepared some nice how-to videos on how to book a flight with Krisflyer miles. There are 2 options – redeeming an award or using miles + cash. If you want to use Krisflyer for partner awards, you have to call them as these aren’t bookable online.
REDEEMING AN AWARD
Keep an eye on the taxes & surcharges. Business class is a better value if you have to pay taxes anyway.
MILES PLUS CASH
If I didn’t have enough to book the award, I would have only used the 20k that were expiring as this isn’t the best use of miles.
