Curves are key in this Melody cabin concept from the in-house Airbus design studio. Flowing shapes evoke feelings of serenity, relaxation, and comfort, Airbus says, and remind us of natural outdoor spaces. A broad winding pathway leads passengers from one end of the cabin to the other, starting with a full galley near the entryway. A master lounge area provides space for private conversations, dining for six, or seats at a bar for socializing. A curved sofa offers a viewing space for a large-screen TV. The master suite features a roomy shower and a massive king-size bed, plus a sofa. The cabin is designed for the ACJ320neo, which carries as many as 25 passengers for flights as long as 7,767 miles at speeds of up to 630 mph. The jet sells for about $95 million, which includes a VIP cabin.
