Airlines wonder if fliers want cell-phone ticketing. Services are being offered to cell phone users, but airlines are reluctant to sell tickets on the wireless Web.

Nobody is more mobile than a frequent flier, so airlines are trying to keep up with the wireless trend. But while several offer simple things such as access to flight data, the companies are hedging on real mobile commerce applications like selling tickets via cell phones.

"The two primary items offered via wireless now are flight schedules and frequent-flier miles," said Ken Smiley, an analyst at Giga Information Group. "Why on earth I'd ever want to use my phone to check my number of miles is beyond me."

Still, airlines continue to offer more and varied wireless information services.

Delta Air Lines this month signed an agreement with AT&T Wireless to provide a direct link to Delta from AT&T's wireless Web service, Digital PocketNet.

Delta has been offering wireless access through Palm handhelds and other wireless devices since March, offering access to flight schedules and itineraries, arrival and departure information, and same-day gate information. But the airline has yet to sell tickets on the wireless Web.

British Airways will announce several mobile Internet services soon, the first part of a US$17.5 million, two year contract with IBM. The service includes graphical seat selectionâ€"the user sees a little picture of the seating chart and picks accordinglyâ€"as well as access to departure and arrival information from Wireless Application Protocol phones.

IBM's Pervasive Computing Group is gaining business with several airlines. As with most things wireless, those businesses in Europe and Asia are ahead.

Japan Air Lines, using NTT DoCoMo's iMode service, offers both wireless reservations and ticket sales. Swissair offers check-in from wireless phones and has plans to sell tickets wirelessly as well, according to IBM officials.

IBM provides back-end hardwareâ€"usually an RS/6000 serverâ€"as well as trans-coding software to translate HTML content to a smaller format. Smaller companies are also getting into the fray. Goldenware now offers Palm query applications that let customers receive flight information from both American Airlines and Continental Airlines. Also, online travel companies like Travelocity.com and Expedia.com, as well as wireless-specific companies like Mobiloc ity. are looking into wireless personalisation services for travelers.

Travel businesses in the United States have been slow to adopt more sophisticated and potentially risky wireless services like ticket sales.

"The airlines are holding off on allowing people to book tickets via wireless because the integration with those back-end systems is more difficult, and there are many security concerns involved," Giga's Smiley said.

Even hardcore wireless device users seemed hesitant about the idea. "It's a tough call at this point," said Michael Steinberg, head of the New England Palm Users Group, in Cambridge, USA. "If there were [an] additional government standard in place, like what some of the financial service firms are doing, then I'd be more comfortable doing it."

Officials at IBM said that airlines are slowly warming up to the idea of wireless ticketing and that upcoming security protocols for wireless networks may speed up the adoption of such services. The next version of the Global System for Mobile Communications will enable the use of digital certificates on mobile phones.

Beyond that, airlines are not convinced that customers necessarily want to buy tickets wirelessly. Just because something is technically possible, even secure, doesn't mean it's practical.

Delta has no immediate plans to sell tickets wirelessly because customers don't seem interested. The airline polled several frequent fliers about various wireless options, and "it didn't fall in the top third percentage in terms of features they wanted," said Toby Pratt, wireless project coordinator in Delta's e-Business Development Group. Because of that, "to date, security for delta.com wireless applications has been of minimal concern due primarily to the fact we don't yet support wireless monetary transactions," said Andrew Ronfeldt, a manager in Delta's IT group.

Delta does use standard encryption for its current wireless offerings, but ultimately, the airline is dependent on the security capabilities of the service provider, Ronfeldt said.

Delta plans to roll out its Virtual Check-in service to its frequent fliers. Currently in beta tests, the service lets customers dial-in and check flight information via an automated voice response system. Financial service companies may have been the first to make wireless sales because their experience with back-end integration gives them a technological edge.

"When they think about what mobile folks want, they don't think of ticketing first," said Michael Karasick, chief technology officer of IBM's Pervasive Computing Group, "I think of the ability to change thingsâ€"changing your seat, changing your reservation on the fly."
