The holiday season represents one of the busiest travel times of the year. Air travel will see the biggest increase in volume during the Thanksgiving holiday with 4.45 million Americans expected to fly, according to the American Automobile Association. (Even more will travel by car, with AAA putting that number at 49.3 million, the most since 2005). With the rise of low cost carriers, airlines are competing to gain more passengers and are looking for ways to make their flying experiences standout. Travel-related technology companies that offer rewards and other services to airlines are attracting buyers, such as Sabre Corp. (Nasdaq: SABR) and Pros (NYSE: PRO). The International Air Transport Association predicts that passenger growth will double in the next 20 years. Pros says airlines want to take ownership of the entire travel journey by converting window shoppers into booked customers. “To meet travelers’ changing expectations while increasing profitability, airlines need a technology partner that is ready to deliver tomorrow’s technological solutions today,” says Sabre CEO Sean Menke. Sabre bought airline technology companies Farelogix and Radixx, while Pros made a deal for digital services firm Travelaer SAS.
