Hello
I am trying to book an award reservation with the following route.
ORD-MAA-SIN-ORD. I have received conflcting info from different reservation agents.
1. One agent indicated that as long as the infant STARTED the journey before she turned 2, she WOULD NOT need a ticket on the return journey. Is this true?
2. I am going to be using partners. If the ticket is issued by AA, then is it AA rules or should I consider the rules of the partner airlines?

Appreciate your help

cheers
