Abu Dhabi-based Etihad Airways has submitted an expression of interest (EoI) to buy a stake in Jet Airways within weeks of wanting to exit the venture completely. Etihad holds a 24 per cent stake in the Naresh Goyal-founded airline, which is left with just 14 planes and minuscule flights. Struggling with a mounting debt of more than Rs 8,500 crore, Jet on Thursday cancelled all international operations along with several domestic flights. While the airline said the cancellations were for a day, indications are that the flights may remain grounded unless there’s an emergency fund infusion.
