At 17 years old, not exactly in a position to start giving tickets to
grandchildren 
but...
For me, the part that attracts me themost is daydreaming about what I
could do with the miles. As it stands, I can almost redeem the miles for a First Class ticket from Asia to US, but I am collecting even more to redeem more lucrative journeys. Hopefully, Star will start a RTW award ticket soon...
I have to agree though, once I have children, I would be delighted to redeem miles for tickets for them. Watching the smiles will alone be worth the miles...!
