Tata Sons, the holding company of Tata Group, is expected to discuss the sealing of a deal with ailing carrier Jet Airways on Friday. The board meet of Tata Sons comes amid media speculation that the salt-to-software conglomerate, Tata Group, wants to buy a controlling stake in the Naresh Goyal-led Jet Airways. The cash-starved airline has been struggling to pay its dues on time. Abu Dhabi-based Etihad Airways has a 24 per cent stake in the cash-starved airline, while Mr Goyal owns 51 per cent.
