Singapore Airlines (SQ, Singapore Changi) is interested in the proposed new Boeing middle-of-the-market (MoM) jet but, if ordered, could place it with one of the Singapore Airlines Group subsidiaries, such as Scoot (TR, Singapore Changi), CEO Goh Choon Phong has been quoted as saying by Aviation Week.

"We will continue to look at it and explore if it will fit into our plan. It would be not necessarily for Singapore Airlines, but for the group," Goh Choon Phong has said.

Singapore Airlines is already an important Boeing customer. According to the ch-aviation fleets module, the carrier operates eighteen B777-200(ER)s, five B777-300s, twenty-seven B777-300(ER)s, and recently took delivery of the maiden B787-10. It has a further forty-nine B787-10s, as well as twenty B777-9s on order with the manufacturer. For its part, the low-cost unit Scoot operates ten B787-8s and six B787-9s. Another group unit, SilkAir, currently operates seventeen B737-800s and three B737-8s, with a further thirty-four aircraft of the latter type on order.

In February, Delta Air Lines said that it is actively engaged with Boeing regarding the proposed new aircraft and hopes to become the launch operator. United Airlines has also included the type as one of many possible replacements for its B757 and B767 jets.

Boeing revealed some details of its MoM jet during the 2017 Paris Air Show, but has yet to firm the aircraft's configuration. The US manufacturer is planning to draw heavily on designs of the B777 and B787 programmes, use composites to a large extent, and is considering a loosely defined "hybrid cross-section".
