Pat, I would call and confirm with MS one more time. I've always gotten confirmations in the other persons name, as long as I gave MS the name when making the initial reservation. If you changed the name after the reservation was made, that could be why the confirmatin is incorrect.
Or, maybe there has been some changes in the MS computer system over the last few months, and only the owners name prints on the hard copy? There have been a lot of policy changes lately.
