Exactly what I was thinking. Seats don't seem any smaller than they were when I was first on an airplane ~16 years ago. Found this article which shows how much seats have actually changed in the past 30 years. The seats have only become a whole 2 inches smaller, which doesn't seem like enough to complain about. Honestly the only problem I've ever had with planes is cramped knees, but I'm pretty tall so whatever. I'm also flying across the country in half of a fucking day so who the hell am I to complain?
