Cheapflights.com has compiled its list of Social And Mobile Airline Services -- a table charting the e-services offered by 24 popular domestic and foreign airlines including their mobile sites, mobile apps, loyalty programmes and special discounts with links to their social media outlets: Facebook pages, Twitter feeds and YouTube channels.

According to Cheapflights.com, notable airlines that are paving the social way are as follows:

Alaska Airlines – For a regional airline, Alaska does social media and e-services as well as the best of the biggest national carriers, including a recently redesigned mobile app that passengers can use to plan every aspect of their trip, down to seating assignments.

Delta Air Lines – Delta combines social media and e-services extremely well, making especially strong use of its YouTube channel.

JetBlue Airways – Even without a standalone mobile app, JetBlue really gets “it.” The discount airline interacts continuously with more than 1.6 million Twitter followers, answering customer requests in a near instant fashion.

Southwest Airlines – With the largest amount of YouTube videos (7 million and counting), 1.6 million Facebook likes and more than a million Twitter followers, Southwest stands out as a leader in online communication with its audience.

United Airlines – Since beginning to merge with Continental, United’s combined e-services presence is even more robust. With fully functional mobile sites, downloadable apps for each airline, a consolidated social media presence - under United’s brand and logo – the airline has potential to be the heaviest social hitter out there.
