According to a Boeing press release and ATWOnline Boeing has finalized an order for up to 100 737 that was announced at this years Farnbourough airshow.
This is good news for Boeing and the 737 line. Most will be for the MAX (75) and some will be NG (10). The rest is an option for more -800NG.
With Boeing and Airbus enjoying good sales, this might be good news for the 160Seat CSeries as well, since the other two now are sold out for a long time!
