Shares of Jet Airways were locked in a 5 per cent upper circuit at ₹ 75.60 on the BSE a day after its new owners announced a revival plan for the ailing airline, which halted operations in April last year due to bankruptcy amid piles of debt. A consortium, led by the Dubai-based entrepreneur Murari Lal Jalan and London-based Kalrock Capital in a statement said, "The Jet 2.0 program is aimed at reviving the past glory of Jet Airways, with a fresh set of processes and systems to ensure greater efficiency and productivity across all routes."
