Mumbai: Around five companies have shown an interest in picking up stakes in Jet Airways that have been put up for sale by lenders in order to put the airline back on its feet, two sources aware of the matter said. The airline has received expressions of interest (EoIs) from them. The news came as the Jet's lenders extended the deadline to submit an EoI by two more days, in the hope that Etihad Airways, which is not ready to budge from its previous stance of not wanting to invest in the airline further, could come around.
