Delta Air Lines is buying an additional 15 Airbus A321 planes to replace smaller, less-efficient aircraft.
The 15 planes come on top of 30 A321s Atlanta-based Delta ordered last year. The airline said the new 192-seat planes will improve the flying experience for customers.
Delta did not disclose the value of the deal, but the list price for an A321 is $110.1 million.
The first A321 will begin flying for Delta in early 2016, with in-flight wi-fi, live satellite TV and other entertainment. The 15 additional planes will be delivered starting in 2018.
