Alitalia’s rescue by Italy’s state-owned railway and investors including US carrier Delta may still be weeks away despite a looming deadline for offers for the loss-plagued carrier, people familiar with the matter said. Ferrovie dello Stato SpA is set to tell the carrier on Monday that its rescue plan has attracted potential investors, including Delta and Atlantia, the people said. Atlantia, the Benetton family’s industrial arm that operates Rome’s airports, on Sunday confirmed its interest to Ferrovie’s adviser Mediobanca, but said it may want changes to the rescue designed by the state-controlled railroad, the people said. Deputy PM Luigi Di Maio, who is leading the latest effort to save the flagship carrier, has been forced to relax the government’s Monday deadline for binding offers and will now accept an expression of interest, according to an official in Di Maio’s economic development ministry. Ferrovie and Atlantia declined to comment. Delta confirmed its interest in becoming a minority shareholder.<br/>
