Philtranco was established in 1914 when Mr. Albert Louis Ammen and Mr. Max Blouse organized the AL Ammen Transportation Company (ALATCO), operating passenger buses from Iriga to Naga.

In 1958, ownership was transferred to the Tuason family, and just before Martial Law, in 1971, to the Mantrade Group. It was then known as Pantranco South Express, Inc. (PSEI)

After a period of crisis and through many creditors and reconstruction, by the early 1970s the company began to stabilize business again. In 1979, the company expanded into the eastern Visayas and began ferry operations in the San Bernardino Strait three years later. In 1984, the company officially changed its name to Philtranco Service Enterprises, Inc.

The company supported the Strong Republic Nautical Highway 2002 project of the government which opened opportunities for trade, commerce and tourism in the western Visayan corridor of the country.

In 2003, the Philtranco central station was built at the heart of Pasay City. It features an automated passenger and baggage check-in system, fully air-conditioned pre-departure area, and a 24/7 staff committed to maintain the safety, orderliness and cleanliness of the station.

The company continued to open more routes from Manila to Diosdado Macapagal International Airport in Clark, Pampanga and to Subic in 2004. By 2005, the Cubao joint terminal in Quezon City was built.
