I paid for the "upgrade" behind the empty exit row on a transatlantic flight once and it was kind of the worst flight I ever had. Usually only my legs hurt from being cramped in but on that flight we were somehow sitting directly in the vent of the A/C - it was the first time I needed a blanket and had a sore throat after just a few hours in the plane. Getting up and moving 3m to the left it was completely fine, so surely not just coincidentally getting a cold... And the entertainment/cupholder foldout thingy also was really flimsy and weird.
