Delta is investing billions of dollars in airport facilities and global products, services and technology to enhance the customer experience in the air and on the ground. Installing full flat-bed seats in Delta One onboard widebody international aircraft is a major component of Delta's investment. This investment also includes Delta's new Terminal 4 at New York-JFK and Maynard H. Jackson Jr. International Terminal in Atlanta, which opened in April 2012. Delta is also spending more than $100 million to expand, renovate and consolidate terminals C and D at New York-LaGuardia Airport. Additionally, customers will see Delta's investment in its more than 50 Delta Sky Clubs throughout the system, power poles at dozens of airports, mobile apps which include features such as baggage tracking, and Wi-Fi on more than 940 aircraft.
