EWR-PBI on a K fare - later this month. standard $159 BUY UP offer immediately after purchase. After ticketed, went back to check and see if price changed and still showing $159 to upgrade. Will most likely cancel ticket (within 24 hours) and just use AMEX PLAT points for J and not play the waiting game for a possibly OLCI $$99-119. At $301 in J after rebates 19K points it's pretty reasonable.
