NEWARK, N.J. (AP) -- Passengers at New Jersey's Newark Liberty International Airport will always get a smile from this customer service representative. Just don't ask her to carry luggage.

That's because she's an avatar.

The Port Authority on Friday will unveil the computerized, hologram-like image named "Ava" in the international arrivals area in Terminal B on Friday. She's programmed to answer passengers' most frequently-asked questions.

The Port Authority is spending $180,000 to place the high-tech help at Newark, Kennedy and LaGuardia airports.
