That's why I gave you row 55 pricing. It's 2nd from the back, the rearmost row with all 9 seats available at the time of looking. I don't know why you're so confident there's no window upcharge when you can clearly verify for yourself that there is, in fact, a way to get it to show you different pricing. Somehow, you're convinced picking true basic class is not valid because it's so poor.
That's a funny edit you added to the parent comment. In your very first comment, you asked "We're [sic] are people paying extra for a window seat?" and then two different people showed you. Amazing.
