Collins Aerospace has developed a concept for the last row of economy planes, "SkyNook," which offers more space for carry-on luggage and is screened off from aisle or bathroom noise. The concept was showcased at the Aircraft Interiors Expo in Hamburg, Germany. While the seats look similar to regular economy class fixtures, SkyNook uses the space between the window seat and the plane's sidewall to create a serene retreat. The design also includes a sliding divider that reduces cabin noise and reduces odor from the galley and bathroom. The company claimed first place in the passenger comfort category of the Crystal Cabin Award at the Hamburg expo.
