My fiance and I are flying via Lufthansa tomorrow afternoon, and reserved seats ahead of time. Our main concern is that we are able to sit next to each other. Honestly, I will probably cry (especially given that I will probably be both sleep-deprived and anxious) if we end up not seated next to one another.

When we went to check in today, we got this warning: "Unfortunately, the pre-reserved seat for MY NAME on the journey from Chicago O'Hare to Frankfurt is currently not available due to operational reasons." Apparently his seat is still available? I don't know.

But when I closed this alert, the page it took me to still shows our seats as being those that we originally reserved, and doesn't act as though either is unavailable. I even called Lufthansa customer service and they said it looked to them as if our seats were available and next to each other, that everything looked fine.

Do I need to select different seats for us? Or is it ok to leave the seats as is? I just don't want to be screwed when we try to board our flight and the idea of going to the trouble of pre-reserving seats and ending up NOT next to each other is making me both extremely pissed and extremely panicked. Any advice would be incredibly appreciated.
