I'm looking to go from LAX-DXB-CDG with a stopover in DXB. I have 100k in my account and 75k in my wifes. Right now I'm seeing availability for J for 2, would it better to call in to make the reservation? If so, can I book my wife's ticket for her? Or does she have to call? Or book it online first with our separate accounts, then call in to add the stopover?

Thanks!
