If approved, any departing passengers arriving by car would be dropped off just short of the departures hall at a newly built drop-off area which would be free to use. Pedestrians would then complete the rest of their journey on foot under a covered walkway.
Any drivers picking up people arriving in the Island would be routed down a new road at the northern end of the Airport – near to the existing Jersey Airlines hangar – and to the short-stay car park. A 20-minute free-parking zone is being considered.
According to the plans, taxis and buses would be able to access an area immediately adjacent to the existing arrivals terminal.
Alares House is also due to be demolished and a new car-hire kiosk built.
Ports of Jersey have been forced to implement the changes as a result of the introduction of Civil Aviation Authority regulations which were introduced in the wake of the Glasgow Airport attack in 2007.
During the terrorist incident, two men drove a car, loaded with propane cannisters, into the doors of the terminal at 30mph, causing the vehicle to catch fire.
In order to conform with the rules, no public vehicles are allowed within 30 metres of an airport building.
It is also hoped that the changes would improve pedestrian safety.
Subject to planning approval, work is expected to start in the autumn.
