Air Deccan was to commence operations on Jamshedpur- Kolkata route by September 30 last year.
The Union minister of state for civil aviation said the carrier did not have the 19-seater aircraft required for the flight service and had to import the aircraft, recruit pilots and other crew members, which caused the delay.
"We have given them the last chance to start the service from February 15. And we will allot it to some other aviation company if they fail to meet the deadline," he told reporters.
Sinha said the steel city Jamshedpur is an important industrial and business centre, and flight service is required to improve air connectivity.
