Nam Air Boeing 737 Seat MapsNam Air

Business class is an airline class above economy and premium economy classes with upgraded amenities, service, and seating. While business class is a significant upgrade over said economy, or the slightly cushier premium economy, it is still a step below the top-of-the-line first class on 737-500 when available.

When you purchase an economy class ticket on 737-500, it means you are sitting in the main cabin, and not located in first or business class. Seats are smaller and packed more closely together, and in-flight services are limited. Economy class seats on domestic routes usually have a seat pitch ranging from a very tight 27 to a generous 32 inches (68.5 - 81 cm).
