Unless you are saying that they are now offering ridiculously cheap upgrade offers (like
this recent post where the OP believed they could redeem from W to J on LAX-CDG for 10,000 miles!)
Haven't there been reports of occasional mileage upgrades to LP in the 100.000-120.000 miles range? upgrading a business class ticket for that mileage price might be cheaper than buying the 265.000miles award ticket.
