Fliers within the U.S. heading to mountain resorts for the holidays can receive free Wi-Fi on AirTran, Delta, and Virgin American. Meanwhile, American Airlines announced a new code-sharing arrangement with airberlin, which will provide service to more than 160 cities in Europe, Russia, the Middle East, and North America.

Providers are doing what they can to oblige, as more and more travelers demand Wi-Fi access in the hotels they choose and the flights they use when they must stay in touch with the office or want to be in contact with friends and family.

The free Gogo® Inflight Internet service will remain available at no cost until Jan. 2, 2011. Gogo is part of Google Chrome.

Sundar Pichai, Google's vice president of product management, says, "Whether it be building a better browser with Chrome or bringing free Wi-Fi to air travelers this holiday season, we are constantly innovating to ensure users' access to the Web is fast, simple and seamless."

These three carriers have outfitted their entire domestic fleet with in-flight Wi-Fi. This promotion will bring free Internet service to more than 700 planes and approximately 15 million expected passengers this holiday season.

"We are constantly working to help provide a better web experience to users around the world,"  Pichai said. "Whether it be building a better browser with Chrome or bringing free Wi-Fi to air travelers this holiday season, we are constantly innovating to ensure users' access to the web is fast, simple and seamless."

This season marks the second straight year that Google has provided free Wi-fi to travelers over the holiday season. Google worked with Virgin America as well as more than 50 airports to provide free Internet both on the ground and in the air last year.

Google launched Chrome as its Web browser two years ago.

American Airlines has launched its codeshare relationship with airberlin, the second largest carrier in Germany, the fifth largest in Europe, and a oneworld® member-elect. With hubs in Berlin and Dusseldorf, airberlin offers more than 160 destinations for fliers on American's network.

American and American Eagle serve nearly 200 cities in North, South and Central America. American offers nonstop service to 56 cities from New York's John F. Kennedy (JFK) gateway. American offers service to 30 cities in Mexico, Central and South America from its Miami hub, the most of any airline. It is also the leading carrier to the Caribbean serving 23 island destinations, as well as service to six destinations in the Bahamas. American serves 31 cities from Los Angeles, including four Hawaiian destinations, Tokyo and, soon, Shanghai, China.

American's codeshare agreement with airberlin also extends to Austrian-based airline NIKI, a strategic partner of airberlin.

"We are very pleased to launch our codeshare partnership with airberlin, which offers our customers the choice of more cities throughout Europe and a more convenient travel experience," said Virasb Vahidi, American's Chief Commercial Officer.

"The codeshare with American Airlines helps to improve the airberlin network in the United States and provides a foundation for further growth. In addition, passengers flying from the U.S. to our hubs Berlin and Dusseldorf now have the possibility to connect to the multiple airberlin destinations in Germany and Europe," says Ulf Huttmeyer, Chief Financial Officer, airberlin.

The agreement also allows AAdvantage® members traveling on codeshare flights (booked under the AA flight number) operated by airberlin or NIKI to earn miles in American's AAdvantage frequent flyer program.
