The incident happened when one of the planes was taxiing and the other was getting ready for take off.
The Air Traffic Control (ATC) gave permission to Jet Airways 9W 730 from Delhi to Patna for taxiing on runway 29 at 2.48 PM. It then allowed the airlines' 9W 603 flight from Delhi to Srinagar to taxi on the same runway at 2.53 PM.
The Patna-bound aircraft had 115 passengers and eight crew members on board while the Delhi-Srinagar flight had 137 people including eight crew.
The airline says it has reported the event to the regulatory authorities. It has de-rostered both the sets of cockpit crew pending investigation.
Engineers of the Jet Airways are inspecting the two aircraft, an official statement said.
All passengers and crew on board the two aircraft were safe and being taken to the terminal. They will be accommodated on subsequent flights, the statement added.
