Angle-Flat
Definition: An angle-flat seat is a business class seat that reclines to approximately 160–170 degrees rather than a full 180-degree lie-flat position, creating a slight incline when fully reclined.
Angle-flat seats were common in business class before the widespread adoption of fully lie-flat seats. They recline significantly more than economy seats but stop short of a fully horizontal position, typically reaching 160–170 degrees.
While angle-flat seats are increasingly rare on long-haul routes, they can still be found on some airlines’ older aircraft, regional routes, and short-to-medium-haul business class. Passengers may slide forward during sleep due to the incline, which many travellers find uncomfortable on overnight flights.
When booking business class, it’s important to check whether your specific aircraft offers a lie-flat or angle-flat product. BookMyBusinessClass agents can advise on the exact seat type for your route and recommend alternatives if an angle-flat product is scheduled. On long-haul flights, a true lie-flat seat makes a significant difference to sleep quality.
