Boeing and United Airlines on June 20, 2017 announced an agreement at the 2017 Paris Air Show to convert 100 of its current 737 MAX orders into 737 MAX 10s, becoming the largest single 737 MAX 10 customer in the world.
United also announced an order for four additional 777-300 ER aircraft.
United expects to begin taking delivery of the 737 MAX 10 in late 2020.
United has flown nearly every version of the 737 that Boeing has produced. The new 737 MAX 10 will add to that legacy, providing United with another in a long line of highly successful aircraft.
