I need to book an award for an adult and child. There Is only 1 saver and i can't book the child separately online. Could I first book the adult online then call in to have them to book the child at the advantage level (assuming availability) and link the reservation together
or do I call and have them do both tickets individually. Is this even possible? Or am I forced to pay advantage for both tickets?

I was able to do this w EVA.
