Boeing's newest aircraft - the 737 Max 10 - has already caught the attention of aviation companies as the US plane manufacturer is in talks with firms for initial sales, said a report.

The roster of potential buyers of the largest-ever 737, which is expected to launch this month, includes Indonesia’s Lion Air, Jet Airways, Spice Jet and Copa Holdings, said a report in Bloomberg.

Boeing is looking to gain ground on a fast-selling A321neo, which is capturing trans-continental routes once dominated by Boeing’s out-of-production 757.

The Max 10 talks aren’t final. A spokesman for Chicago-based Boeing declined to comment on the talks, the report said.

The newest 737 Max would seat around 230 passengers in a single-cabin layout common among LCCs or 189 passengers in two-class capacity. At a length of 43.8 meters (only a modest 1.68 m or two rows longer than the MAX 9), the new variant does not require a thorough re-design, the only major change being the trailinig-link landing gear modification. This means that the model can be fitted with same wing and CFM LEAP 1B engines as the MAX 9.

“We aren’t looking to simply build something on par with the A321neo,” said Randy Tinseth, a Boeing vice president for marketing. “We’re bringing a better airplane to the market -- and that’s our focus.”

United Continental Holdings Inc. is studying whether to convert 61 orders for the 737 Max to the -10 version, while taking a handful of Boeing 777-300ERs, the largest twin-engine jetliner currently flying, persons close to the matter said.

Chief executive officer Oscar Munoz said United, the third-largest US carrier, was “interested” in the Max 10, during a brief interview on the sidelines of the International Air Transport Association meeting in Cancun, Mexico, this week.
