Air India has been allocated rights to operate nearly 20,000 weekly seats to Hong Kong, Dubai, Qatar, Singapore and the UK that were previously used by Jet Airways.
Civil aviation minister of state Hardeep Singh Puri disclosed the rights awards to Air India and its Air India Express unit in a written question to India's Rayja Sabha, which are temporary until the end of the 2019 scheduling season.
Compared to existing schedules, Air India has the potential to significantly increase capacity on most routes, and for the first time will give it access to the Qatar market.
The flag carrier was also awarded domestic slots to operate 22 services, mostly from Delhi, Chennai and Bengaluru.
No details on seat awards to other carriers were disclosed by Puri, however SpiceJet has previously been awarded a number of Jet's former routes, and had been expecting more in future.
IndiGo and Vistara are also expected to seek some of the former Jet allocations.
