If your friend always flies with a companion (free E+), check in a lot of luggage (free 3 for self, 2 for companion), fly int'l itin (free *A clubs), and plan to fly a lot next year (100% RDM bonus) - only then it's worth it. In most cases it's not, and will be difficult to recoup $1400 worth of benefits. That said, if your friend can turn SIN MR into a non-MR and see the place. Take some pictures and enjoy the trip, then the actual amount spent for status can be valued lower.
