On that flight, I didn't. I usually sit by the window and have a view of what's happening. Maybe ask to sit by the window, and think of what the pilot's are doing at that moment. Watch what the plane is doing, using what view you have, and think about how that's what it should be doing. For instance, on approach to Denver, I had a window seat. I could tell exactly when the pilot took over for the autopilot, just from watching how the wing was rolling and pitching more now than a minute before. Another thing I did was print approach, arrival, and departure charts, and take a watch to time how long each segment was.
