I did an OLCI for tomorrow's flight earlier this morning. I'm a Gold Velocity Member, travelling on a flexible ticket and I checked in with a Sequence Number of 2. I had been auto-allocated Seat 4D. Whilst I'm generally happy with 4D, my preference for early morning flights is to have a window seat so I can lean against the wall and sleep. So I looked at what other options were available. Despite my status, the flexibility of my fare and the fact that I was only the second person to check in, I couldn't have a window seat forward of Row 15 (out of interest, nor was it possible to have a different aisle seat other than 4D forward of Row 15). I've found this sort of thing happen more than once, but I don't understand it...
