American aviation major Boeing has signaled its intent to unveil a modified version of its 737 MAX 10 aircraft at the opening of the Paris Airshow on Monday this week.

The 190-230-seat 737 MAX 10 aircraft will boast more seats and a revamped landing gear. The new version of the narrow body medium-haul family will help the plane manufacturer to plug the existing gap against Airbus.

Boeing Commercial Airplanes CEO Kevin McAllister also dismissed concerns by financiers regarding fragmentation of the 737 MAX-family into five separate models.

Speaking on the topic, CEO McAllister said, “We are working very closely with a large number of customers, with offers on the table … There is significant demand for each model.”

Analysts have predicted that the world will need as many as 41,000 commercial planes over the next two decades. The estimated figure represents an increase of 4 per cent from last year's Boeing forecast. Last week, Airbus forecast 34,899 commercial jets over the same period.

The Chicago-based aircraft maker is expected to announce more details at the imminent Paris Airshow.
