Smit Machchhar told Indian Prime Minister Narendra Modi how he managed to avert disaster during Wednesday’s incident on a Dubai to Tel Aviv flight.
Mr Machchhar has been hailed as a hero after his actions allowed passengers to enter the cockpit and subdue the co-pilot as the jet plunged thousands of feet.
Speaking in an emotional video call from hospital in Abu Dhabi, he described how he fell to the floor after the stabbing and was “fighting for my life”.
“When I was down, I could feel that the aircraft was plummeting, and I knew this is a last chance to do something. I knew the door was just there,” said Mr Machchhar.
Despite still getting hit by the attacker, he said he managed to open the door and “knew that I could not let people die”.
Mr Modi told the Flydubai captain: “The whole country can proudly say that we Indians are not people who take lives, we are people who save lives.
“And you had such a big wound on your body, you yourself were fighting for life and death. At that time, you did not care for your life, you cared for the lives of all the travellers.”
India’s embassy in the UAE has said Mr Machchhar is recovering and in “good health”.
The co-pilot, an Omani national, was arrested and Israeli Prime Minister Benjamin Netanyahu has suggested the incident could have been “another 9/11”.
Four passengers on the flight have said the co-pilot said “kill me” after he was restrained.
More than 170 people – mainly Israelis – were on board, with people describing how the plane lurched out of control during the incident.
One of the passengers who entered the cockpit said he pulled up on the yoke to level the aircraft before two off-duty pilots took over and landed the plane in Tabuk, Saudi Arabia.
Images of the plane showed damage to its rudder, likely caused by its rapid descent when no one was in control.
