Delta will add 100 state-of-the-art, fuel-efficient Boeing 737 MAX aircraft to its fleet, with options for 30 more. Most importantly, Bastian said, “This aircraft will be piloted, served and maintained by the very best professionals in the business, and it’s their hard work and dedication to our customers that always sets us apart.”. The MAX 7 has a range of 3,850 nautical miles (7,130 kilometers), while the MAX 8 and 9 have a slightly lower range of 3,550 nautical miles (6,570 kilometers). This allows the aircraft to narrowly beat the 3,500 NM (6,482 km) mark set by the A320neo but still comes in below the A321neo's 4,000 NM (7,408 km). The Boeing 737 MAX 9 offers the same swWFY4h.
