Using up a minor's points
My 5 year old has earned about 6,000 points. We're taking a short one way flight this summer, where each ticket costs about 5K points.
How can I use her points?
Can I mix two sets of points on a single reservation, either starting from my account or from hers? Should I book her separately, even though that might trigger her as an unaccompanied minor?
Thanks!
