Wouldn't count on it. Most people want to fly as cheaply as possible, also after corona. So airliners will keep on maximising seats per plane. Moreover, decreasing seats per plane will increase emission per passenger, so it also makes no sense from an environmental perspective. So it's more likely that you're going to pay more for the same "stuffed into a tube like cattle" experience.
