The fiercely competitive airline business is turning to technology in the battle for customers.

Since American Airlines began testing Wi-Fi service on live flights in August 2007 and JetBlue Airways began its BetaBlue project in December 2007, other airlines are following suit, including Delta Air Lines and Virgin Atlantic Airways.
