yeah this might have to do with the ps reconfiguration. in the old ps planes, 1-3 are first class, so maybe there is a discrepancy between the seat maps and the booking class for that particular flight. you might be able to call and have someone override it if it is that important to be in rows 1-3. i dont fly ps but my understanding is that on the new product the business class cabin is more than 3 rows...?
