Service 24 is a loop trunk route between Ang Mo Kio and Changi Airport, serving Serangoon, Upper Paya Lebar, Paya Lebar, Eunos, Bedok and Upper Changi. Introduced as part of the 1983 Changi Airport Bus Plan, it replaces previously existing bus routes and remains today as a unique connection along much of its route. This service duplicates the East-West Line between Paya Lebar and Tanah Merah, and closely follows Service 22 between Ang Mo Kio and MacPherson.
Due to the loop-route nature of Service 24, as well as irregular demand across the day, this route is very prone to bunching-up. Sectors of high demand are between Bedok and Upper Changi where the route connects to private housing and new developments along Upper Changi Road East.
Service 24 serves Changi Airport Terminals 3, 1, 2 & 4 in order.
Changi Airport Passenger Terminal Buildings (PTBs) 1, 2 and 3 have their bus stops integrated into their basement levels, which also serves as a cargo loading and unloading bay. Security checks for any unattended or suspicious articles are carried out before a bus enters Terminals 1, 2 and 3. Bus Captains may take a short toilet break at Terminal 2. Because of height restrictions, double-decker buses are unable to enter Changi Airport basement.
Occasionally when Changi Airport basement is closed, buses will be diverted to the departure hall along T1/T2/T3 Departure Drive where a temporary bus stop will be set up.
Announcements for passengers to inform the Bus Captain if they see any suspicious person or article are played on board public buses at Changi Airport as well.
