The hijacker, whose motives remained a mystery, was arrested after giving himself up.
Eighty-one people, including 21 foreigners and 15 crew, were onboard the Airbus 320 flight when it took off, Egypt's Civil Aviation Ministry said in a statement.
Conflicting theories emerged about the hijacker's motives. Cypriot officials said early on that the incident did not appear related to terrorism, while the Cypriot state broadcaster said he had demanded the release of women prisoners in Egypt.
Speaking to reporters after the crisis ended, Egyptian Prime Minister Sherif Ismail said the hijacker was an Egyptian national.
"At some moments he asked to meet with a representative of the European Union and at other points he asked to go to another airport but there was nothing specific," he said. The man will now be questioned to figure out what his motives were.
Cypriot foreign ministry official Alexandros Zenon told reporters during the crisis that the hijacker appeared to be "unstable".
Egypt's Civil Aviation Ministry said the plane's pilot, Omar al-Gammal, had informed authorities that he was threatened by a passenger who claimed to be wearing a suicide explosives belt and forced him to divert the plane to Larnaca.

The hijacker’s demands remain unknown, or at least cannot be stated publicly. “Up to now we have not had any effective demands that we can announce,” Egypt’s Minister of Civil Aviation Sherif Fathy Ateyya says.
Comments purportedly from Samaha and read out by the BBC said passengers initially did not know the plane had been seized. Crew took their passports and they noticed the plane was gaining height rather than descending to Cairo. They were then told they were going to Cyprus, he said, according to The Guardian,
