Public transportation in the United States is represented by domestic flights, buses, railroads, and subways.
1. Domestic flights
Flying is a convenient way to travel across the United States from one city to another. However, tickets are not cheap. If you book them at least five days in advance, you can save between 25% and 40%. Popular domestic airlines include Southwest Airlines and Virgin America.
2. Intercity buses
Another convenient way to travel between cities and states is by intercity bus. The most popular companies are Greyhound Bus Lines and Megabus.
3. Urban Transportation
U.S. cities typically have bus systems, and some also have subway systems. Each state's transportation system may have its own specific rules and quirks. When taking the bus, you usually pay your fare directly to the driver. Keep in mind that it's common not to receive change, so make sure to have the correct fare in advance.
4. Taxis
Taxis in the United States can be relatively expensive, and fares are typically metered. You can book a taxi through your hotel, by phone, or simply hail one on the street.
