Delta Air Lines recently announced plans to expand in-flight Wi-Fi to its international fleet of aircraft beginning in early 2013, reports MSNBC. More than 150 of Delta's international fleet of Boeing aircrafts will receive the new satellite-based Internet service, as will the Airbus A330 aircraft.

Although Delta already operates 550 airplanes equipped with Wi-Fi for domestic flights -- making it the world's largest fleet with Internet access -- the transatlantic planes will have Internet access is projected to be completed by 2015. In addition, over 200 Delta Connection regional jets have Gogo Inflight Internet.
Pricing for the international Internet service is not known yet, but Delta's website says it sells 24-hour passes for $12, monthly passes for $34.95 and an annual subscription for $399.95. "Delta's advancements in technology have been a key component to our improvements in the customer travel experience," said the airline's senior vice president of marketing, Tim Mapes, via press release.

Delta already has competition, however. MSNBC reports that United Airlines also plans to install Wi-Fi to its entire fleet of aircraft beginning later this year. That company also plans to finish the upgrades by 2015, but both of these American companies might be a bit behind the curve. International carriers, like Lufthansa and Singapore Airlines, already offer transoceanic Wi-Fi to their customers.
