Expedia and adding my niece

[kkozma]

I have a delta reservation for my family of 4 and need to add my niece, I probably just have to call, but it seems there is no other way to get a single airline ticket for a 13 year old. It does not appear there is any way to add to a current reservation online.
thanks for any suggestions.
