After years of delays and cost overruns, Boeing has finished the FAA certification process for its KC-46 Pegasus military tanker.

Boeing maintained its massive lead over Airbus in terms of 2018 orders during the month of May.

The aircraft manufacturer is celebrating the pending entry-into-service of the jet model — but the 2020 arrival of the slightly larger and more efficient 737 MAX 10 will render it superfluous.

The 737 MAX 10 would offer huge unit cost advantages over the planes that Alaska Airlines has inherited from Virgin America. Upgrading to Boeing's newest plane could thus help Alaska Air rebuild its profit margin.

UPS ordered 14 Boeing 747-8 freighters worth $5.65 billion.Since 2016, UPS has ordered 28 Boeing 747-8 freighters. These aircraft are essentially all that is left of Boeing's 747 order book. UPS also ordered four Boeing 767 freighters worth $848.8 million.

Last week, Delta Air Lines completed a long-awaited order for next-generation narrowbody planes. But its decision may have had more to do with engines than with the aircraft themselves.

Boeing is closing out 2017 on a high note following an order slowdown that lasted from July until the middle of October.
