Delta Air Lines Completes Wi-Fi Installation on Nearly Half of its Domestic Fleet May 11, 2009 ATLANTA , May 11, 2009 -- Delta Air Lines (NYSE: DAL) today announced that it has installed Wi-Fi on nearly half of its domestic mainline fleet, making the airline the world’s leading provider of in-flight connectivity. Of the more than 300 airplanes Delta operates on U.S. routes, 139 are equipped with Gogo® Inflight Internet, including the entire MD-88 fleet. In addition, the MD-90 fleet will be complete by the end of May with the remainder of the domestic fleet scheduled for completion by September. Delta offers more Wi-Fi onboard than any airline worldwide. “In response to the interests of our customers, Delta is the market leader in providing in-flight Wi-Fi and is well on its way to offering guaranteed Wi-Fi every time our customers fly a mainline flight within the continental United States,” said Tim Mapes, Delta’s senior vice president – Marketing. “We are fully committed to investing in innovative on-board technology that adds value for our customers be it in the form of seat-back satellite TV, on-demand movies or now Wi-Fi.” Delta made a commitment last year to equip its entire domestic fleet with Wi-Fi, allowing more travelers to use their electronic devices on airplanes to surf the Internet, access e-mail and send instant messages. The airline later expanded its installation plans to include approximately 200 pre-merger Northwest airplanes which are slated for completion next year. Once complete, Delta will have more than 500 aircraft offering Wi-Fi. In addition to the MD-88s, Wi-Fi is now available on select 757-200s and MD-90s. Service is offered in both First and Economy class on a pay-per-flight basis. The cost of Wi-Fi access on a single Delta flight ranges from $7.95-$12.95. In June, customers also will be able to purchase month-long, unlimited use passes. On the ground, Delta has expanded free Wi-Fi access to include all visitors to Delta Sky Club lounges within the United States. Effective immediately, access cards formerly provided in pre-merger Delta lounges are no longer necessary to access Wi-Fi networks in Delta Sky Clubs. Delta Air Lines is the world’s largest airline. From its hubs in Atlanta, Cincinnati, Detroit, Memphis, Minneapolis-St. Paul, New York-JFK, Salt Lake City, Paris-Charles de Gaulle, Amsterdam and Tokyo-Narita, Delta, its Northwest subsidiary and Delta Connection carriers offer service to 370 destinations in 66 countries and serve more than 170 million passengers each year.
