India's troubled airline SpiceJet has resumed flights after it agreed to pay oil companies cash for fuel purchases. The fleet of the debt-ridden carrier, which owes money to creditors, including oil companies, was grounded for several hours on Wednesday. The cancellations left thousand of angry travellers stranded at airports across the country. SpiceJet, India's fourth-biggest airline by market share, has $314m (£200m) in debts. The company has been unable to pay its dues to staff, airports, tax authorities and its lenders. "We have resumed operations [from Wednesday evening]. We paid [oil companies] in cash at some airports," news agency AFP quoted a source in SpiceJet as saying. The airline cancelled nearly 1,900 flights last week and on Wednesday, it did not operate more than 150 of the 243 scheduled flights, reports said.
