a few random thoughts... your daughter is going on a purchased ticket, i assume.
if it is important for her to accrue mi's, then i would worry about the fare basis. otherwise, buy the cheapest ticket you can get.
i have had reasonable quotes from qantas vacations and would suggest getting quotes from them.
i don't know about usair but for discount fares, qf gives 70% of mi's to aa. unless you are on an aa code share.
edit to add... is she on a packaged trip? if so i would suggest you talk to the people running the thing.
btw.. welcome to ft. over a few days the questions will resolve themselves and a lot of info will be provided.
