Jet Airways (JAI, Mumbai International) has announced it would undertake a "comprehensive review" of its network in order to trim unprofitable routes and improve the financial results.

"The strategy includes concentration of capacity, enhancing frequency, density and hub connectivity. The measures will include rationalisation of operations on select, uneconomic routes and the redeployment of these assets to more productive and economically efficient international as well as domestic sectors," the Indian carrier said in a statement.

So far, few details have been revealed as to what exactly will this review entail.

Jet Airways said that it would use its new B737-8s to replace older generation narrowbodies on select routes.

The carrier also said that it would launch new services and/or additional frequencies to Singapore Changi from Mumbai International, Delhi International, and Pune in November and December. It also added flights from Mumbai to Manchester International earlier this month.

Despite the planned restructuring of the network, the overall capacity measured in ASKs should remain flat, the airline said.

"The airline continues to engage with financial stakeholders for supporting its funding requirements till it starts generating operational surplus and is actively working on the monetization of its assets and capital infusion," Jet Airways also said.

As of June 2018, Jet Airways had a gross debt of INR86.2 billion rupees (USD1.2 billion), while its accumulated losses stood at INR108.8 billion rupees (USD1.5 billion).
