In the Op-Ups I've had over the years, I don't think I've had one where it's just me and not my travel companion too.
I had one from ET to CE last year and we were put in different rows, although the guy at the gate asked if we wanted to be downgraded again in order to sit together. No was our collective answer, and as it was we appealed to the better nature of another CE traveller to swap seats anyway.
