MINNEAPOLIS (AP) -- Delta Air Lines said on Wednesday that it will buy 40 more Airbus planes, once again grabbing jets that may have been under-appreciated by other airlines.
Delta said it signed a firm order for 30 Airbus A321s, which tend to be used on domestic flights, and 10 A330s, a larger plane used for international flights. Delta already has 158 planes from those two families of jets by way of its 2008 purchase of Northwest Airlines.
The deal would be worth some $5.6 billion at list prices, although discounts are common.
Both of the Airbus types ordered by Delta are widely-used and well-thought-of. But demand is slowing.
Delta is buying a version of the A321 that is being phased out in favor of a "new engine option" that Airbus plans to begin delivering in 2015. The new version is more fuel-efficient and has been getting the bulk of new orders. But the old version that Delta is buying costs $10 million less per plane.
For the A330, Airbus had booked just 11 orders through the end of July, while delivering 57 of the passenger version of that plane. As of April it had orders for another 280 of those jets, but it has been building them faster than new orders are coming in.
Delta CEO Richard Anderson called the Airbus deal "another opportunistic fleet transaction for Delta in which we acquire economically efficient, proven-technology aircraft."
The new-plane smell is rare at Delta.
It's getting used Boeing 717s from Southwest Airlines, which got them when it bought AirTran but didn't want to keep them. Delta will use them in part to replace DC-9s that are an average of 35 years old.
Delta has also bought dozens of used MD-90s, last built in 2000. And it has delayed delivery of Boeing's new 787 until 2020, while competitors such as United Airlines are flying that long-haul jet now.
It does buy some new planes — Delta is taking new Boeing 737-900s later this month. Its most recent new-plane delivery was in December 2010.
Delta will begin getting the new A330s in early 2015. The first new A321s arrive in early 2016.
Airbus said it expects to assemble many of Delta's A321s at the new plant it is building in Mobile, Ala., which is scheduled to deliver its first planes in 2016.
