CNN) -- American Airlines is investigating reports that a pilot asked passengers to identify themselves as Christians so non-Christians on board could talk to them about their faith, a spokesman has said.
Spokesman Tim Kincaid said on Sunday the incident reportedly happened Friday on Flight 34 from Los Angeles, California, to John F. Kennedy International Airport in New York City.
"It is under investigation," Kincaid said. "We've had some complaints about it."
Kincaid said the pilot, whose name was not released, reportedly asked Christian passengers to raise their hands before suggesting that the other passengers should discuss Christianity with those passengers.
The pilot, who had just returned from a mission to Costa Rica, reportedly said he would be available at the end of the flight for further discussion, Kincaid said.
"We're investigating to learn the facts," Kincaid said. "That would be against our policy if it did happen."
The pilot was not scheduled to fly during the weekend, the airline said.
