Economy Class: Why The Name “Coach?” It all dates back to the 15th century in the town of Kocs (pronounced rather like “coach”), Hungary. That’s where a large four-wheeled carriage called a “coach wagon” was first popularized. By the 17th century, stagecoaches were used to deliver mail as well as for transportation. These operations were mechanized during the Industrial Revolution, but the old-fashioned “coach” name stuck. In the mid-1800s, only first-class railroad cars were called “coaches.” Over time, however, all the cars became coaches. As the exclusivity of the term “coach” declined, it became associated with the cheap seats.
