The cabin cross section of the aircraft family was designed to give enhanced seating comfort for passengers, with features like broader seats and armrests for the middle passenger and larger windows at every seat to give every passenger the physical and psychological advantages of ample natural light. The cabin featured large, rotating overhead storage bins, allowing each passenger to stow a sizeable carry-on bag overhead. Bombardier claimed that compared to the cabins of current in-service narrowbody aircraft, the aircraft family would provide airlines with the highest overhead bin volume per passenger and a wider aisle that allows for faster boarding and disembarkation of passengers.
