This is a setback for the largest private carrier whose co-founders Rahul Bhatia and Rakesh Gangwal are reported to have differences over control of the airline and are taking legal advice from experts.
Most private carriers want traffic rights for lucrative short-haul destinations such as Dubai, Doha, Dhaka, Singapore and Bangkok.
"Everybody wants rights for foreign routes where capacity is not going to be an issue after Air India mounts flights. The airlines have been advised to plan those routes which are under-served or have seen a spike in air fares after Jet Airways suspended its operation," said a person aware of the development.
Civil aviation secretary Pradeep Singh Kharola chaired a meeting with top airlines CEOs on Friday to discuss re-allocation of unused foreign rights of Jet Airways.
"The rights would be given on a temporary basis and for the ongoing summer schedule," said an executive of a private airline.
He said that demand made by SpiceJet and IndiGo are almost same with both the carriers wanting more seat quota on the India-Gulf sector.
"Singapore and Bangkok are another routes airlines want to fly more seats," the executive said.
IndiGo is learnt to have shown keen interest to fly about 8,000 more seats on India-Dubai sector besides asking additional frequency to Dhaka.
"The airlines have been asked to come out with fresh suggestions. This will be analyzed before final decision on allocation,a an official said.
Preferring Air India over the private carriers, the civil aviation ministry earlier this week decided to allot about 5,700 weekly seats to the airline out of grounded Jet Airways' unused quota on the lucrative India-Dubai route.
The public sector airline was also promised over 5,000 seats on India-Qatar route besides about 4,600 additional seats to and from London.
The state-run airline would be launching new flights to Dubai from Delhi and Mumbai from June 1 utilizing the fresh seats allocated to it out of Jet's unused rights.
