In Parliament, Prime Minister Julia Gillard blamed Qantas for leaving thousands of passengers stranded in Australia and around the world, insisting the airline didn't need to take the "extreme" action of grounding its entire fleet for 48 hours over a labor dispute. Qantas CEO Alan Joyce repeatedly said the dispute over pay and job security gave him little option but to ground the fleet. On Monday, an arbitration court ordered an end to labor strikes, which had forced the cancellation of 600 flights in recent months, disrupted travel for 70,000 customers and cost Qantas $75 million.
