An air stewardess also posed for a picture with AirEgypt hijacker Seif al-Din Mohamed Mostafa while he was wearing what was initially thought to be a suicide belt.
Cabin crew member Naira Atef is seen smiling next to the 58-year-old, who took passengers and crew hostage during a tense five-hour stand-off on Tuesday.
The picture emerged on Facebook after British Ben Innes, 26, also posted a picture of himself smiling next to Mostafa while being held captive on board the A320 jet.
Video footage has emerged of Innes asking a crew member to take the picture with the hijacker, who was threatening to blow up the plane.
Innes, from Leeds, defended posing for the shot, arguing that he was just trying to stay “cheerful in the face of adversity”.

He told The Sun: “I’m not sure why I did it – I just threw caution to the wind while trying to stay cheerful in the face of adversity.
"I figured if his bomb was real I’d have nothing to lose anyway, so took a chance to get closer and look at it.
"So I stood by him and smiled for the camera while a stewardess did the snap.”
The plane was forced to land in Larnaca, Cyprus, over fears that a terrorist incident was taking place.
Cypriot authorities later accused him of diverting the Alexandria-to-Cairo flight.
Mostafa demanded to see his Cypriot ex-wife and his children, while pictures appeared to show him wearing an explosive device which later turned out to be fake.
He eventually surrendered and faces possible charges of hijacking, kidnapping, reckless and threatening behaviour, and breaches of the anti-terror law.
The Egyptian is currently being held in custody.
