Reply from LTA: As the fare model for the different types of bus
services are not proportional, the key to unbiased fares is the
adoption of a fundamental fare scheme that is used by all services
travelled on a single journey. The fundamental scheme is then
extended with surcharges for other type of services. This is
necessary to ensure that the same combination of services and
distances will always be charged at the same fare even when they
are used in the reversed order.
The difference in fare model between the air-con and non air-con
buses is due to the air-con surcharge. Commuters are charged
between 5 to 25 cents for travelling on the air-con services in the
journey. In your instance, the total
distance travelled on air-con services (bus 985 and MRT between
Bukit Batok and Boon Lay) has reached the maximum 25 cents of
air-con surcharge to be deducted. As such, commuters who use the
non air-con service 246 as part of this journey will not see any
difference in the total fare with commuters who travel on full
air-con services along this same journey. We have checked
and wish to assure you that the mentioned fares are deducted
correctly.
