The government is reviewing the wide-body lease pact between IndiGo and Turkish Airlines, which is set to expire on May 31.
Renewal of the leasing agreement is unlikely due to security concerns and strained bilateral ties with Turkey.
India has been distancing itself from Turkey due to its defense cooperation with Pakistan, leading to a potential non-renewal of the current pact.
IndiGo has been operating Airbus A330s on lease from Turkish Airlines for its Istanbul flights and defended the collaboration as essential for providing international access to Indian flyers.
