Pretty amazing how much like a fighter a commercial plane can be. Especially when it isn't hauling 200 fatboys weighing in at 200 pounds each (40,000#) + another hundred pounds each (20,000#) in the luggage compartment! Sixty thousand pounds less makes a BIG difference.
I remember when I solo'd in a Cherokee 140 @ Monroe Airport. My instructor weighed about 225. He warned me when he got out and before he walked to the tower: "This plane is going to climb faster and float longer without my weight. Think about that and plan accordingly." It was amazing enough that I remember that today more than 40 years later!
