"SpiceJet is in talks with IndiGo to purchase 7.5 per cent equity in the airline," an industry source told PTI on condition of anonymity, but key officials of both SpiceJet and IndiGo refused to comment on what they called rumours and market speculation.
SpiceJet is also looking for a position on the IndiGo Board, the source said, adding that "they are still discussing what the price should be".
SpiceJet Chief Executive Officer Sanjay Aggarwal said, "We do not comment on such rumours and speculations".
IndiGo Airlines President Aditya Ghosh, said, "As a company policy, we do not comment on rumours". However, the two air-carriers are understood to have already held several rounds of discussions on the issue.
SpiceJet has even appointed a merchant banker for this purpose, the source said.
But Spicejet had no plans for merger, the source said. "The deal is simply for purchasing equity and not any merger. Both the airlines have different types of aircraft and separate management control. So a merger may be difficult." the source said.
