A French court began the process of liquidating insolvent airline Aigle Azur Monday but left bidders including Air France-KLM and Air Caraibes 2 more days to come back with an acceptable rescue plan, the CFDT union said. The Evry commercial court ordered Aigle Azur's liquidation under a "going concern" process that leaves more time before assets are sold off, setting a midnight deadline Wednesday for bidders to improve their offers. Air France, which submitted an initial proposal last week, has agreed to combine its bid with Air Caraibes parent Dubreuil group, two sources said. Monday's decision buys time for the resubmission of a joint plan. Air France wants to buy Aigle Azur's medium-haul business serving Algeria and the surrounding region, along with valuable take-off and landing slots at Paris Orly. <br/>
