Boeing's 737 MAX is the latest update of its popular, single-aisle, twin-engine aircraft. Boeing has about 5,000 planes on back order ,selling at about 0 million each. The fuel-efficient plane has a range of 3,215 to 3,825 miles (about 5,954 to 7,084 kilometers). The aircraft is offered in four lengths and seats 138 to 230 passengers.

Boeing MAX jets were grounded worldwide following crashes March 10 in Ethiopia and October 29, 2018, in Indonesia that killed a total of 346 passengers and crew. Preliminary investigations suggest the aircraft's MCAS, an automated anti-stall device, apparently forced the noses of Lion Air and Ethiopian Airlines flights down and into a fatal plunge when it erroneously determined the planes were about to stall. To avoid a stall, MCAS points the nose of the plane down to gain air speed.

Boeing is having ongoing conversations with airlines about possible reimbursements following the worldwide grounding of it 737 Max jets. All of the 13 Chinese airlines that own Max planes have requested compensation, and further steps might be taken, an industry expert said.
