Yes, United Airlines offers lie-flat beds in its premium business class cabins, most notably within the "United Polaris" service. This product is specifically designed for long-haul international flights and select transcontinental routes (such as New York to Los Angeles or San Francisco). The Polaris seats transition into a fully flat bed that is 6 feet 6 inches long, providing a comfortable sleeping surface. To enhance the experience, United partners with Saks Fifth Avenue for high-quality bedding, including plush duvets and pillows. Depending on the aircraft type—such as the Boeing 787 Dreamliner, 777-300ER, or 767—the configuration is usually 1-2-1, ensuring that every passenger has direct aisle access. Even on some older aircraft or narrower planes used for shorter "United Business" routes (like those to Latin America or the Caribbean), you may find "cradle" seats, but the true lie-flat experience is the hallmark of the international Polaris brand.
