Sydney ( CNN ) -- Australia 's Qantas Airways said Tuesday its flights are back to normal after a government labor board ordered it to end a dispute with its unions that grounded the airline over the weekend . `` Qantas sincerely regrets the impact on customers of industrial action over recent months and looks forward to a rapid recovery and period of stability , '' the airline said in a statement . Most international passengers were accommodated on flights Monday and overnight , while the backlog of domestic passengers is expected to be cleared by early Tuesday afternoon , said Qantas , which resumed flights on Monday . The first planes to depart were an international flight from Sydney to Jakarta and a domestic route from Melbourne to Sydney . Some 100,000 passengers were affected by the groundings , said Kira Reed , an airline representative . Labor relations tribunal Fair Work Australia ordered an end to the labor dispute `` to avoid significant damage to the tourism industry '' after Qantas grounded its jets Saturday afternoon . The airline grounded 447 flights and , ahead of the order to end the dispute , had announced it would lock out its unionized pilots ; engineers ; and ramp , baggage and catering crews effective Monday evening . The dispute with the unions has dragged on for 14 months , the labor board said . Qantas argued that the unions ' demands would leave the airline `` seriously impaired or destroyed . '' The labor board gave the two sides three weeks to reach an agreement , with a possible three-week extension if talks were making progress . The decision `` provides certainty for Qantas passengers , '' company CEO Alan Joyce said in a statement following the decision . He apologized to passengers . The Australian and International Pilots Association said it hoped for a `` positive outcome '' from the talks , calling the decision to ground the airline a `` gross overreaction '' to its demands . `` It is a sign that the current management has lost touch with the traveling public , its workers and the basic Australian ethos of free speech , '' the union said in a statement . The labor dispute involves three unions representing air and ground staff of Australia 's largest domestic and international airline . Union officials have accused Qantas of planning to outsource ground jobs at a cost of thousands of Australian jobs and of putting profits first . Pay and working conditions have also been at the center of the dispute . Qantas , which has its headquarters in Sydney , is the second-oldest airline in the world , and marked its 90th anniversary last year . It employs about 32,500 people and flies to more than 180 destinations worldwide , according to the company website . CNN 's Hugh Williams and Pamela Boykoff contributed to this report .
