Delta to Become Only Major U.S. Airline to Offer Broadband Wi-Fi Access on Entire Domestic Mainline Fleet Aircell's Gogo inflight Internet service to be available in first and economy classes on more than 330 Delta aircraft in 2009, the most expansive inflight broadband offering of any U.S. air carrier ATLANTA, Aug. 5, 2008 – Delta Air Lines (NYSE: DAL) customers traveling throughout the continental United States will soon be offered the added convenience of broadband Wi-Fi access onboard the airline's domestic fleet of more than 330 mainline aircraft. Delta is joining with Aircell®, a 17-year leader in airborne communications for business and commercial aviation, to install the company's Mobile Broadband Network on the carrier's domestic fleet. The system, Gogo™, will enable Delta customers traveling with Wi-Fi enabled devices, such as laptops, smartphones and PDAs, to access the Internet, corporate VPNs, corporate and personal e-mail accounts, as well as SMS texting and instant messaging services. Gogo will be available to customers for a flat fee of $9.95 on flights of three hours or less, and $12.95 on flights of more than three hours. "Delta remains committed to providing a travel experience that maximizes the time our customers spend with us onboard by offering them even more productivity options," said Richard Anderson, Delta's chief executive officer. "Our customers asked for in-flight connectivity, and we're responding by rolling out the most extensive Wi-Fi network in the sky. Beginning this fall, our passengers will have the ability to stay connected when they travel with us throughout the continental U.S." Gogo will be offered initially on Delta's fleet of 133 MD88/90 aircraft and will rapidly expand to the remaining domestic fleet of more than 200 Boeing 737, 757 and 767-300 aircraft throughout the first half of 2009. The airline expects to have more than 330 aircraft complete by summer 2009. The full fleet agreement between Aircell and Delta will provide a consistent, convenient experience for customers traveling on the airline who wish to use the Gogo Internet service. "The advent of Air-To-Ground (ATG) technology has made broadband connectivity in the cabin economically viable for the first time for commercial airlines," said Jack Blumenstein, President and CEO, Aircell. "The game has changed and Delta will be among the first to provide an enhanced customer experience with broadband Wi-Fi access on more than 1,000 daily flights within the U.S." In addition to being the most cost-effective in-flight broadband technology available, the Aircell system is extremely light, requires minimal space on the aircraft and is installed overnight, making it a sound investment in a competitive, high fuel-price environment.
