United Airlines is looking to add a sleek new airframe to its fleet.

The airline on Thursday announced that its investment arm, United Airlines Ventures, is directing an undisclosed amount of funding to JetZero—a startup developing a blended wing body (BWB) design. The company said its conditional purchase agreement with JetZero “includes a path” to order up to 100 BWB aircraft, with the option to double its order if JetZero satisfies certain performance milestones, such as the flight of a full-scale demonstrator in 2027. It will also need to meet United criteria for safety, business, and operations.
