SAN FRANCISCO, Jan. 30 (Xinhua) -- U.S. leading aircraft manufacturer Boeing Company said Tuesday that it is celebrating with TUI group, the world's major tourism operator, the delivery of the operator's first 737 MAX 8 model.

Technological upgrading and improvement have made the MAX model the fastest selling airplane in Boeing history with more than 4,300 orders to date from 92 customers worldwide, said the top U.S. aerospace leader.

"The 737 MAX is a great fit for TUI Group, with 14 percent lower carbon emissions and a 40 percent smaller noise footprint supporting its airlines commitment to sustainability," said Monty Oliver, vice president of European Sales of Boeing Commercial Airplanes.

TUI Group, based in Hanover and Berlin of Germany, has 51 additional orders of the 737 MAX 8 and four 787 Dreamliners.

The group, which also has 18 unfilled orders for the 737 MAX 10, is the first European operator to select the latest and largest member of the 737 MAX family of airplanes.

The German tourism giant with 67,000 employees operates six airlines across Europe and approximately 150 medium and long-haul aircraft, which serves more than 20 million customers in 180 destinations around the world.
