Europe’s Lufthansa Group agreed to buy four widebody jets valued at $1.4 billion from Boeing Co.

The purchase of the twin-aisle 777s provides Lufthansa subsidiary Swiss International Air two additional 386-passenger planes on top of the airline’s 10 existing 777s. It also gives Lufthansa Cargo two additional air freighters. The two businesses are part of a sprawling network that also includes Austrian Airlines and Eurowings.
