Not working for me. Selecting only the original segments, clicking Next through all the segments, removing the eUpgrade request... on the summary page the seats selected don't change and the continue button is greyed out.
Tried multiple browsers on iOS/Windows/Mac, regular vs private mode...
Edit - I'll post to the seat blocking thread, but it seems like 2 passengers on a widebody Comfort booking - I can't choose A and C seats. Call centre agent noticed this, and when I tried on the website, it finally allowed me to change seats as long as I didn't leave a seat between the 2 passengers on the booking. A and C were not allowed.. but AB / BC / CD were allowed.
