It says, "Hello and welcome to Washington Dulles International Airport."
It's "Paige," a life-size hologram with a friendly smile. She dishes out airport and flight information passengers may need coming off international flights and she's catching lots of curious stares because she looks so real.
The downside for some passengers is that Paige can't respond to them, meaning she's not able to answer questions, but she's been a big hit so far. Airport officials say they may install more holograms like her at the airport.
