Jet Airways Ltd has agreed to most conditions set by shareholder Etihad Airways for offering a lifeline to the debt-laden Indian carrier, the Business Standard newspaper said, sending Jet’s shares soaring as much as 18 percent on Friday. Both airlines are set to sign a memorandum of understanding (MoU) within days, which would result in Jet Airways’ founder and chairman Naresh Goyal reducing his stake to 22 percent from 51 percent and stepping down from the board, the report said.
