I've been checking in MMB to see if the seat map appears prior to OLCI which, having read several helpful posts on here, it seems to do. Our flight is Sunday 13th, VS85 to Vegas. I checked this morning and saw the seat map had appeared a full 26 hours before OLCI opens up.
All seats in PE were showing as free, but the system would not accept my request for any seat, even though they were all showing as available for selection. Every time I tried to select a seat the system just displayed a message - "this seat is unavailable - your current seat is unchanged". I continued to keep trying every half hour or so until, about 4 hours later, all seats suddenly appeared as unavailable with VS allocating us 77A and 77C in the bubble. We're actually quite happy with those - Mrs QH was really worried that we would be allocated in PE downstairs.
It seems that seats are being firmly allocated by VS prior to OLCI and if the flight is full/busy, there's no opportunity to select your preferred seat.
