if it was to change a letter then there could be a small fee (if its not the airlines mistake) but if its a complete name change then it should be a new ticket

when you purchase a nonrefundable/no flex ticket you get exactly that which you agreed to when purchasing the ticket, you had the opportunity to purchase a refundable ticket but chose to pay the cheapest ticket which offers no protection, if they just add fees to change this and that then no one would buy flexible tix and that would then increase the avg price of tickets to maintain profitability
