BERLIN (Reuters) - Insolvent German airline Air Berlin <AB1.DE> has not yet exhausted a 150 million euro ($179 million) bridge loan, a spokeswoman for the Economy Ministry said on Friday.


The government agreed in mid-August to provide the loan to ensure that Air Berlin flights continue for a period of up to three months, to return holidaymakers to Germany and secure thousands of jobs.


Beate Baron, spokeswoman for the Economy Ministry, said the loan was being paid out in tranches according to demand.


"The credit has not been exhausted," she told a regular government news conference, adding she could give no further details as to how much has already been disbursed.
