The first MAX 7 will now undergo system checks, fueling and engine runs on the flight line in Renton. The airplane, the first of two MAX 7 flight test airplanes, will begin its flight testing program in the coming weeks.

The 737 MAX 7 is scheduled to enter service in 2019, following delivery to launch customer Southwest Airlines.

The entire 737 MAX family is designed to offer customers exceptional performance, with lower per-seat costs and an extended range that will open up new destinations in the single-aisle market. The MAX 8 entered service with customers across the globe last year, and the MAX 9 will start deliveries in the coming months. The MAX 10 was launched at last year's Paris Air Show and is scheduled to enter service in the 2020 timeframe.
