American aircraft manufacturer Boeing rolled out the first 737 MAX 9 yesterday, its latest update to the the 737 family after the MAX 8, which is due for delivery in May.
Recent orders for the MAX family number over 3,600, but the newest update to the best selling jet in history faces stiff competition from European rival Airbus' A321 neo.
Boeing's updates to the original 737 series feature new engines and aerodynamic enhancements that will "upgrade your profitability," claims the company.
The MAX 9 carries 220 passengers and flies 3,515 miles nonstop, a step up from the MAX 8 unveiled last year.
However, the A321 flies even further while carrying more passengers, and until Farnborough last year in July was outselling the MAX 9 five to one.
The Max 9 occupies aircraft serving the middle of the market, or short- and medium-haul routes.
But out of the 3,600 MAX orders, the MAX 9 has reportedly only sold 220, prompting concern that Boeing might have to consider a MAX 10 to fend claw back interest.
