My AvantGo recently surveyed it users to see what travel services they want for their PDA when on the road.

According to the company, the survey, conducted entirely via mobile devices, found that travelers are most interested in mobile access to flight delay alerts, airline schedules, driving directions, weather updates and airport maps.

"By their very nature PDAs are an indispensable tool for travelers, delivering critical information when it is most needed, even en route to the airport," said Neil Versen, senior director of My AvantGo at iAnywhere Solutions. "With this latest survey, we sought to identify consumer travel and purchasing preferences to help our customers in the travel sector best plan and provide services for the My AvantGo user base."

The company said results of the recent My AvantGo Travel Survey show that travel decisions are primarily driven by price, followed by schedule, convenience and frequent flier accounts. Online travel has grown to the point that nearly a third of respondents reported that they purchased 100 percent of their travel online last year. The survey also found that more than 65% of survey participants would be interested in receiving travel discounts on their PDAs, while 67% desire flight delay notifications via mobile devices. Driving directions, weather, flight schedules, flight status and airport maps also top PDA wish lists.

According to survey results, American Airlines, Continental and United are the most frequently flown airlines among respondents. Respondents also indicated that their most popular hotel destinations are Marriott Hotels & Resorts, Holiday Inn Hotels & Resorts and Hilton. In the rental car category, respondents identified Hertz as the most popular rental car agency for purchases, with Avis and Budget close behind.

My AvantGo offers travel channels from airline carriers, global travel organizations, travel content providers and online booking agents. Earlier this month, My AvantGo expanded its travel section with the launch of an American Airlines channel.
