SunExpress (XQ, Antalya) has modified its Boeing (BOE, Washington National) order book, the US manufacturer has revealed in its latest update for August 2017.

In February 2014, SunExpress ordered fifty aircraft from Boeing consisting of forty B737-800s and B737-8s with ten options. Deliveries were to have run from 2015 through to 2021.

However, according to Boeing, the Turkish leisure specialist placed an order for seven B737 aircraft, while reducing its existing order by seven. As of July 2017, SunExpress's Boeing backlog consisted of seven B737-800s and twenty-five B737 MAX.

SunExpress is a 50/50 joint-venture between Lufthansa (LH, Frankfurt International) and Turkish Airlines (TK, Istanbul Airport). It currently operates fifty-two B737-800s on scheduled and chartered passenger flights connecting Turkey with Western Europe, Scandinavia, and Russia.
