To be honest, there are very few people on the subway in the United States. There are more elderly people and students. They basically drive by car. The one-way ticket is 1.75 dollars, the one-day ticket is 7 dollars, the 7-day ticket is 25 dollars, and the 30-day ticket is 109 dollars. The card fee is $2. If you are traveling by public transport, buying a package is still a good deal.
