S class tickets are often non refundable. You will likely find that you can't just pay a fare difference to upgrade the fare class. If you want the higher fare class you will likely forfeit your original ticket and have to buy a new ticket.
could he pay the 'change fee' and change the fare class that way? my guess is that it's a no since the deep discounted fare class don't accrue full mileage? maybe make a plea to state he accidentally booked the wrong fare class?
