Intercity bus lines are transportation services that connect different cities, allowing passengers to travel between urban areas. These buses typically operate on scheduled routes and offer various amenities, such as comfortable seating and onboard restrooms. They are often a cost-effective alternative to trains and flights, making them popular among budget travelers. Many intercity bus lines provide services across the country, with major companies like Greyhound and Megabus leading the industry. Passengers can purchase tickets online or at bus terminals, and the journey duration varies depending on the distance and number of stops along the route.
