DUBAI (Reuters) - Etihad Airways said on Tuesday it continues to explore options for leisure airline Niki which it bought from Air Berlin <AB1.DE> for 300 million euros ($351 million) earlier this year.


Etihad agreed to buy Niki as part of a deal to create a holiday airline in a joint venture with TUI Group <TUIGn.DE>. Those talks fell apart in June.


Earlier on Tuesday, Air Berlin said it had filed for insolvency. Niki is not part of the insolvency proceedings.


A TUI spokesman said it was in talks with Air Berlin over its wet lease contract with Air Berlin, which sees TUIFly planes leased to Niki.
