Using miles for Youth ticket
I want to use miles for my granddaughter to accompany me (FB Gold) to France next year, but the AF website asks for her DoB (since I selected Youth) and subsequently says I can't use miles.
My question is: Is it not permitted to use miles for a youth (she'll be 13), or is this a website glitch?
Should I just call to book both her spot (with miles) and mine (with money)?
EDIT: As it turned out, they wanted me to purchase my own travel online and then call back to have them book the award ticket, after which they linked the bookings.
Thanks, everybody, for your help!
