Earlier this year two of us booked an award using United miles on United and Austrian Airlines. I can view it on United and click on "View additional confirmation numbers" and see a confirmation number for the Austrian Airlines segment.

When I try to enter this confirmation number on the Austrian Airlines web site, nothing is found.

What am I doing wrong?

I'm trying to check on seats and make sure everything is properly confirmed for a trip in a couple of months.

Thanks.
