Atlanta-based Delta said it is running the three-month pilot project on three gates on Concourse T.
Passengers at gates T1, T2 and T3 will see mobile agent podiums and gate agents with handheld devices to make seat changes and handle other tasks. They will also use turnstile-type "E-gates" that allow passengers to "self-board" by scanning their smart phone or boarding pass.
The podiums for agents take up less space than gate counters, allowing more space for seats at the gate and boarding.
The gates also have boarding pillars that show where passengers should line up for different boarding groups, aimed at better organizing the boarding line.
