Insolvent Air Berlin cancelled dozens more flights Wednesday as pilots again called in sick, despite warnings from the airline that the wildcat action could jeopardise rescue talks.
A deadline to submit bids to acquire Air Berlin or parts of it has been set for 15 September.
But he added that the firm could if necessary buy up all of Air Berlin's assets, including 140 leased aircraft and prized landing and takeoff slots at German airports.
It said at least 32 flights would be canceled on Wednesday, and that it was unable to operate 35 flights for Lufthansa's LHAG.DE budget airline Eurowings.
Air Berlin filed for insolvency in mid-August, after its main shareholder, Gulf carrier Etihad, unexpectedly pulled the plug on its cash lifeline.
The news of Pang's interest comes as Air Berlin is still reeling from mass flight cancellations caused by pilots calling in sick as a form of protest.
"Besides, long-haul flights are not affected as Air Berlin is not operating any Airbus A330 on behalf of Eurowings".
"We are now in final discussions with investors" he said, warning that cancellations were costing the already bankrupt firm "millions of euros". The allowance may reportedly keep the carrier afloat until mid-November with its German jobs put at risk.
An industry source said Air Berlin could lose 4 million to 5 million euros a day because of the cancellations.
Air Berlin made a loss of €782m (£703m) in 2016.
One source has told Reuters that Lufthansa is interested in as many as 90 of Air Berlin's planes.
German service-sector union Verdi argues that it is "not at all surprising" that pilots have called in sick, given Air Berlin's current situation.
