Yes, on nearly all of American Airlines' international and transcontinental long-haul fleet, the Business Class seats (branded as "Flagship® Business") are designed to be "lie-flat." This includes aircraft like the Boeing 777-200, 777-300ER, and 787 Dreamliner, where seats extend into a fully flat bed that is roughly 6.5 feet (2 meters) long. These seats are arranged in a "1-2-1" configuration, ensuring that every passenger has direct aisle access, so you never have to climb over a neighbor. In 2026, American is also rolling out its new Flagship Suite® seats, which feature a sliding door for complete privacy and even more storage space. It is important to distinguish these from domestic "First Class" seats on smaller narrow-body aircraft (like the Boeing 737 or Airbus A321), which are typically "cradle" or "recliner" style seats that do not lay flat. For travelers flying between major hubs like NYC to LAX or London to Dallas, the lie-flat experience is a standard feature, providing a much higher level of comfort and sleep quality than standard domestic premium cabins.
