Delta Air Lines is stepping out from behind the counter at Hartsfield–Jackson Atlanta International. The airline announced Wednesday that it has rolled out 100 handheld devices to “help gate agents drive more personal engagements with customers at its home airport in Atlanta.” Delta’s “Nomad” tool is the size of a cell phone and gives agents the ability to make seat changes, rebook customers, check bag status, board or check-in customers, and print bag tags and boarding passes. Delta says the Nomad devices will save customers time, cut line waits and help Delta teams better adjust staffing when bad weather or other factors impact the operation. After testing the device and gathering feedback at Hartsfield–Jackson, the company says it plans to expand testing to other hub markets. <br/>
