What are the basic methods to transport passengers?

The basic methods to transport passengers at an airport typically include the use of buses or vehicles designed to move people to and from terminals and aircraft, walking directly to the boarding area or aircraft, and using jet bridges that connect the terminal directly to the airplane, providing a seamless transition for passengers from the terminal to the plane.

Buses and vehicles play a crucial role, especially at larger airports where aircraft may be parked at remote stands away from the terminal. Walking is fundamental, as passengers often have to navigate various areas of the airport. The jet bridge enhances convenience, allowing for direct access to the aircraft without the need to go outside, thereby protecting passengers from weather conditions and streamlining the boarding process.

Other methods noted in the other choices, such as helicopters or cargo transport, do not reflect standard passenger transport within the airport context, and while trams and moving walkways contribute to passenger movement in certain settings, they are not universally fundamental methods like the bus/vehicle, walking, and jet bridge combination.
