I work for Ek and I had someone on my last trip ask if the seats on the right side of the plane have more leg room.
I tried to explain to them that we have the same amount of seats/rows on both sides and that the plane is the same length on both sides and that the person on that side with leg space maybe just has shorter legs.
They however did not believe me so they said that on there next flight the are going to request to sit on the right.
