What is the passenger capacity of the Boeing 737-800?

The Boeing 737-800 typically has a maximum passenger capacity of 189 when configured in a high-density layout, which is commonly used by many airlines, including low-cost carriers like Ryanair. This configuration allows the airline to maximize the number of seats available for passengers, optimizing revenue per flight.

While other configurations can accommodate fewer passengers, such as 150 or 180, the standard high-density setup used by Ryanair makes 189 the most accurate representation of its capacity for commercial operations. This choice reflects the aircraft's design and adaptability for various short to medium-haul routes, allowing airlines to efficiently serve a larger number of passengers within the constraints of the aircraft's size and operational capabilities.
