Based on what I've read, I would guess that it would be a little bit higher than €390 for PE to J.
Well, on my last CDG-IAD flight upgrades from W to J were not offered before or during check-in. Asked at the airport and they were asking something in the 800s. J was not very full, but right after the "PNC boarding finished" PA message, the Y to J parade started. When the door was closed, J was full. So carnavon's suggestion might be the more plausible
