In American Samoa, you will find that buses are much different than back home.  We call them the 'aiga bus', which means family bus.  The buses are built locally and must comply with strict safety standards, albeit not quit as strict as most places. 

You can feel safe on the buses and they aren't all that uncomfortable.  The only problem you might run into is loud music.  Most buses have huge sound systems and the drivers like to blast the music as loud as possible.  There are laws limiting volumes on buses but they are not always followed.  You can politely ask that the music be turned down or just don't get on a loud bus.

Bus stops are found throughout the main island of Tutuila, but you can stop and catch a bus from anywhere on the side of the road simply by waving down a bus.  All buses have village names on them and travel from their respective villages to the bus depot at Fagatogo in town and then return.

When you get on the bus, be sure to confirm that the bus is going where you want to go and ask how much the fare is.  You should also be careful not to find yourself at some distant village after buses have stopped running.  Your bus driver will probably be very helpful and tell you what to do.  Most passengers pay the fare as they leave the bus because they might decide to get off before their destination and hope to catch another bus the rest of the way.

There are no bus schedules.  People needing to get to and from work will be familiar with the buses and their approximate schedules.  The buses operate throughout the day with services ending around 5.00pm, Monday to Friday. On Saturday services are reduced and on Sundays only a handful of buses operate. 

Fares and zones
For no more than $2.50 one-way you can travel from the town to either the western or eastern end of Tutuila.  Here is the most recently posted rate sheet for Taxis and Buses.
