Award Reservation Question I will be flying with my wife and child and have a question.  My wife and I each have enough miles to buy our tickets, but not enough to purchase a ticket for our 2 year old child.  If we each use our miles to buy our tickets can we use cash to buy our kid's ticket, or will it not allow us to purchase a single ticket for a 2 year old?  Will we be able to reserve seats together at booking?
