Different last names equal "split" reservations?
I recently made reservations through my travel agent for myself, my wife, and my child. I then accessed the travel reservation details (throught the "View/Change Reservations" link) on nwa.com so I could select seats. I typed in the NWA confirmation number and my last name, only to find that my wife (who has a different last name) was missing. When I went back and typed in the same NWA confirmation number and her last name, I got the travel reservations details page with just her information showing. In the past, we've all always shown up together on the same page. I wonder if something has changed recently...
In any case, my question is, since we are all Silver Elites (and so have some chance of being auto upgraded), will we be treated as a group of three, or as two and one? Is there any other reason to be concerned about this "split" reservation?
