Boeing and International Airlines Group (IAG) announced an order for a combined total of 50 737-8-200s and 737-10s, plus 100 options. The 737-8-200 will enable IAG to configure the airplane with up to 200 seats, increasing revenue potential and reducing fuel consumption. The largest model in the family, the 737-10 seats up to 230 passengers in a single-class configuration and can fly up to 3,300 miles.

The fuel-efficient jet can cover 99% of single-aisle routes, including routes served by 757s. The 737 incorporates the latest-technology CFM International LEAP-1B engines, Advanced Technology winglets and other improvements to deliver the highest efficiency, reliability and passenger comfort in the single-aisle market. The 737 family of airplanes is on average 14% more fuel-efficient than today's most efficient Next-Generation 737s and 20% more efficient than the original Next-Generation 737s when they entered service.

Today's announcement finalizes a commitment made by IAG for the 737 at the 2019 Paris Air Show and is subject to approval by IAG shareholders.
