Traveling in first class on a French TGV (InOui) provides a significantly more spacious and tranquil experience than second class. You get wide, ergonomic seats arranged in a 2+1 configuration, ensuring more elbow room and a "Solo" seat option for privacy. Features include power-recline, adjustable headrests, and individual power sockets at every seat. In 2026, many trains also feature the "OPTIMUM" premium class, which offers access to Grand Voyageur lounges in stations and a fully flexible ticketing policy. On the high-speed Paris–Lyon corridor, the "OPTIMUM PLUS" service adds high-end at-seat dining with porcelain tableware and a dedicated onboard host. You also benefit from dedicated quiet zones, high-speed Wi-Fi, and an entertainment portal with over 500 options ranging from films to international press.
