VIENNA (Reuters) - December salaries will be paid to staff of insolvent airline Niki (>> Air Berlin Plc), whose administrators are working on selling its remaining assets, the head of Niki's works council said on Friday.

Niki filed for insolvency last week after Germany's Lufthansa (>> Lufthansa Group), which is buying other parts of Air Berlin, scrapped plans to buy Niki, grounding the airline's fleet and stranding thousands of passengers.

"I was told that the (December) salaries will be paid," works council chief Stefan Tankovits told Reuters.
