A new mobile service from American Express and Rearden Commerce lets corporate customers access travel information, track changes and make new plans from their BlackBerry smartphones. Down the road, American Express Anywhere will help companies monitor expenses and enforce policy compliance, says Jay Cary vice president of interactive product management at American Express. “It's very easy for someone like a CFO to change that policy with a couple of clicks,” Cary says

The service now offers access to a personalized travel itinerary, real-time travel alerts and destination weather reports, while upgrades are planned that will let users view airport parking, car service and restaurant reservations.
