Boeing 737 MAX-Series

Like the A320neo, the 737 MAX is the latest version of Boeing's long-serving short-to-medium range airliner that it has been selling for 50 years.

For MAX duty, Boeing gave its 737 new engines, wings, avionics, and a slew of other updates. The 737 MAX series is made up of four different variants — the 149-seat 737 MAX7, the 189-seat MAX8, the 200-seat MAX200, and the 220-seat MAX9.

The updated 737 is available with new CFM LEAP-1B turbofan engines. Boeing has more than 3,700 orders for the 737MAX and entered service in May.
