55 passenger jets were ordered by General Electric Co.'s aviation subsidiary from Boeing Co.
Financial terms of the deal were not disclosed. Boeing said the list price for 53 single-aisle 737-800s and two extended-range versions of the widebody 777-300 is $4.5 billion (3.06 billion EUR), but customers typically negotiate steep discounts.
