Not rude, but you might be directed to the ticketing desk to pay for it. It will be the difference between the fare you paid, and the current J fare for the sector you want to fly.Would it be rude upon checking in to ask if there is an available
upgrade from PE to J ?

Thanks MEL_Traveller:Not rude, but you might be directed to the ticketing desk to pay for it. It will be the difference between the fare you paid, and the current J fare for the sector you want to fly.
You might want to look at other options for upgrading prior to arriving at the airport, like mySQupgrade.
