Boeing Co is set to win an order this week from United Continental Holdings Inc for 100 of the plane maker’s 737 jets in a transaction that may be valued at about $8.4 billion, people familiar with the matter say. The accord includes options for as many as 100 more jets and will be announced July 12 in Chicago, where both companies are based, said two of the people, who asked not to be identified because details aren’t public. The order will include the upgraded 737 Max model, the people said. A deal later this week would be a boost for Boeing as it promotes the Max at the Farnborough International Air Show outside London.
