"Third Class" refers to a category of accommodation on trains, ships, or other forms of transportation, typically offering the most basic amenities at a lower price. It is designed for travelers who prioritize affordability over luxury, often featuring shared facilities and less space compared to higher classes. In the context of the Titanic, "Third Class" was the section for lower-income passengers, providing essential services and communal areas. Despite its reputation, many immigrants and working-class individuals found it a vital means of travel to new opportunities in America.
