Bus Service 110 is a trunk service from Buangkok 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 was 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 Terminal 3. Bus Captains may take a short toilet break at Terminal 2. Due to height restrictions, double-decker buses are unable to enter Changi Airport basement.
Occasionally when Changi Airport basement is closed, buses may be diverted to the Departure Halls of the respective terminals, 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.

I really can’t fathom how it is financially and operationally feasible for 110 to be under Woodlands bus pack and having WLDEP as it’s depot. The dead mileage from compassvale int to woodlands dep can’t be good for petrol costs, and also probably causes bus intervals to be irregular and inaccurate.
I strongly feel that 110 should let SBST takeover now that there is SWDEP to take charge.
Most unreliable bus service in terms of bus arrival timings. Honestly disappointing. It used to be okay
