Well, there are at least 6 ticket to sell, including 2 in the cheapest bucket, if you consider KL will overbook J, it probably means there might be 4 or 5 actual seats still available, not including last minute cancellations.
Based on Y availability, OLCI cash upgrade is likely to be very expensive, however I would definitely give a call to the plat line to check for mileage upgrade options.
