If you’ve ever flown on a commercial airplane, you’ve probably noticed that boarding always happens from the left side of the aircraft. This isn’t just a coincidence; there are several reasons, rooted in history, safety, and practicality, that have led to this standard.

A nod to nautical tradition

The practice of boarding from the left side has deep historical roots, dating back to the early days of aviation when many conventions were borrowed from maritime practices. On ships, the left side is known as the “port” side, where loading and unloading of passengers and cargo typically take place. When airplanes started to carry passengers, this tradition carried over, and the left side became the standard for boarding.

Pilot positioning and control

Another key reason for left-side boarding lies in the positioning of the pilot. In most commercial aircraft, the captain’s seat is on the left. By boarding passengers from the left side, the captain can have a clear view of the boarding process. This vantage point allows the captain to monitor ground activities, communicate effectively with the crew, and ensure that everything is proceeding smoothly before takeoff.

Efficient ground operations

Boarding on the left side also plays a crucial role in the efficient operation of airports and ground services. Typically, the right side of the aircraft is reserved for cargo loading, refueling, and other maintenance activities. By keeping passenger boarding separate from these activities, airlines can minimize the risk of accidents and streamline operations.

Enhancing passenger safety

Safety is a paramount concern in aviation, and the left-side boarding practice contributes to it. By designating the left side for passengers and the right side for cargo and maintenance, airlines ensure that passengers are kept away from potentially dangerous activities, like refueling. This separation also aligns with emergency protocols, as passengers and crew are familiar with the layout and procedures associated with boarding and deboarding from the left side.
