Why Do Passengers Always Board Airplanes from the Left Side?

Question

Is there anyone who observed that whenever we are boarding an aircraft, we always board from the left side? What could be the reason for this?

Answer 1

It's all by design to board from the left side. It enables the pilot who is normally sitting to the left side to properly align the aircraft with the terminal jet bridge. Besides, the right side is sometimes dedicated for re-fueling and load provision, thus embarking from the left side allows the crew to operate freely and minimizes passenger risk. The principle of boarding the aircraft from the left side also simplifies connection of jet bridges to the aircraft.

One of TSA Pre-Check’s benefits is not having to take your laptop out (I think they vetted you I had to give some information then later they approved me for it). I know American Airlines has the wing seats wider, asks 3 times if you're able to help people get off in case of a crash and it gives you more leg space (though you have to pay like $40-60 more probably to offset the lack of an extra seat)
