Biman Bangladesh Airlines Boeing 737 Seat MapsBiman Bangladesh Airlines

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 737-800 when available.

When you purchase an economy class ticket on 737-800, 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).
