Delta Air Lines (NYSE: DAL) will invest more than $770 million through 2016 to refresh the interiors on its Boeing 757-200, 737-800, Airbus A319 and A320 aircraft to provide power at every seat, add new slim-line seats with adjustable headrests, updated lavatories, add more efficient galleys and additional features to improve passenger comfort.

This latest capital investment will improve the service consistency provided to Delta's customers in First Class and Economy cabins as well as increasing aircraft efficiency and overall customer satisfaction of the airline's domestic narrowbody fleet.
The investment continues Delta's multi-year focus on passenger comfort that  that began in 2010. All Delta international widebody aircraft will include full flat-bed seats with direct-aisle access in BusinessElite by mid-2014 and all transcontinental flights will have full flat-bed seats in BusinessElite by summer 2015. The investments have maintained more First Class seats than any U.S. carrier; offer more in-flight entertainment options; provided access to Wi-Fi on all domestic two-class domestic aircraft with expansion to its entire international fleet by 2015; offer Economy Comfort seats on all two-class aircraft to give customers extra legroom; and increase access to power for customers in-flight.
