Thousands of staff at Jet Airways have not received their August salaries as the company battles to preserve cash amid heavy losses. A spokesman for the Jet said Wednesday that 15% of the company’s employees had not yet been paid for August, though he insisted they would be eventually. The company said it was “evaluating various funding options” to address its acute financial problems a day after it made a push for extra cash flow by announcing its largest ever sale, with price cuts of up to a third on 2.5m seats. Jet and its Indian rivals are suffering the effects of much higher fuel costs, which have been driven up by a rise in global crude oil prices and the weakening of the rupee. In India’s fast-growing but still low-income economy, the number of airline customers is rising quickly but they remain highly sensitive to pricing. <br/>
