American Airlines has expanded the range of features available on the mobile version of AA.com, providing more tools for travelers using Web-enabled devices.

The new enhancements allow customers to book flights, view fare specials, request upgrades, enroll in the AAdvantage program, purchase Admirals Club one-day passes and change their flights for many domestic reservations.

These additions complement the features in place when the mobile version of AA.com was launched earlier this year. This includes flight check-in, flight and baggage status checks, destination and weather information and AAdvantage member log-in. Throughout the year, American will add further mobile capabilities for travelers on the go, the airline said. For information: www.AA.com (GD)
