Bus Service 110 is a trunk service from Compassvale to Changi Airport, mainly serving residential estates in Sengkang and transfer passengers at Tampines Expressway (Punggol Road) Transfer Stop with direct connections to Changi Airport and vice versa. The route complements the existing Service 858 for the key link between the TPE (Punggol) Transfer Stop and Changi Airport via a long express sector along TPE and PIE, as compared to Service 27 and 34 between TPE and Changi Airport which takes a longer route through Tampines.

The route also calls at Changi Airport PTB4 Bus Stand in addition to the basement bus stands of three existing terminals, joining Service 24, 34 and 36 at the then newly-opened Terminal 4. It will also serve neighbourhood amenities such as Sengkang Sports Complex and the upcoming Sengkang General Hospital.

The route commences operations on Sunday, 22 October 2017, a week before Terminal 4’s official opening date of 31 October 2017. It is the second SMRT bus service after Service 858 to serve Changi Airport.

Service 110 is the second service to operate out of Compassvale Bus Interchange, after Service 374.

Changi Airport:

Service 110 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 to 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.
