Boeing is trying to assemble a group of airlines willing to buy a new version of the 737 jetliner.
The new model, dubbed the 737 Max 10X, would be longer than the slow selling 737 Max 9, currently the biggest version of the single-aisle airliner.
The Max 10X, if launched, would be the third new or revamped 737 model in as many years and the fifth in Boeing’s lineup. The first Max model delivers this year and the Max 9 follows in 2018.
