Bus Service 110 is a trunk service from Compassvale to Changi Airport, mainly serving residential estates in Sengkang and transfer passengers at Tampines Expressway (Bef / Aft Punggol Rd) 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. On the other hand, Service 27 and 34 between TPE and Changi Airport takes a longer route through Tampines.
The route also calls at Changi Airport Terminal 4 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 also serves neighbourhood amenities such as Sengkang Sports Complex and Sengkang General Hospital.
The route commenced operations on Sunday, 22 October 2017, a week before Terminal 4’s official opening date of 31 October 2017. It is the second SMRT Buses 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. With the closure of Compassvale Int from 1 Dec 2024, Service 110 will be amended to Buangkok Int.
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 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 onboard public buses at Changi Airport as well.

I boarded a man a22 yesterday to changi airpotr
Itzi possible to start 110 bus service first bus timing at 0505 because it will service a lot people working 0600 shift.. ,currently taking bus 27 first bus start at sengkang (aft Bungkok stn)
Pls improve your time, yesterday evening after took from T1 ,travel time back home (67769 bus,1730-1830)
So funny to see that there is no MAN A22s on this service. Its questionable of LTA arrangement.
As of today, sometimes MAN A22 will deploy on 110, as well as SMB Citaros
Hougang-Sengkang contract supposedly to have 30 svc but only 29 so far.LTA out of goodwill awarded SMRT probably SMRT got bendy experience should the service encounter higher loadings in future.944 supposedly to be run by TTS but again LTA awarded to SMRT because of cost issue.
And BSEP already reached its target 80 new service.68 postponed until further notice.
381 is an additional svc for Go-Ahead.944 supposed to be additional svc for TTS but already been compensated by CD 663 & 665.
Argue as you will the truth will prevail
