737MAX

Boeing wants its machinists’ union to accept big concessions on retirement and health benefits in exchange for winning the assembly of the 777X wide-body jet in the Puget Sound region. But machinists are also worried the contract casts doubt on the future of the 737MAX in Renton. 

Boeing had a triumphant announcement today - a big order from United Continental for its 737 narrow-body airplanes, which are made in Renton. United is buying 150 737s, Boeing's popular single-aisle jet. Two-thirds of those planes will be the newest version – the 737MAX, which Boeing announced last August.

Boeing was rushing to catch up with its rival Airbus, which had already announced hundreds of orders for its new narrow-body plane, the A320neo. Randy Tinseth is a vice president of marketing for Boeing.
