UPDATE 1-Lufthansa submits new AUA remedy offer

* Lufthansa says submitted new offer on AUA takeover bid

* EU Commission says will study the offer (Recasts with Lufthansa confirmation)

BRUSSELS/FRANKFURT, July 16 (Reuters) - Lufthansa (LHAG.DE) has submitted a new remedied offer to the European Commission aimed at tackling antitrust concerns over the carrier's plan to buy Austrian Airlines (AUA) AUAV.VI, the German company said.

The commission said late on Thursday it will study the offer carefully but could not make any further comment at this stage.

Difficulties with the proposed takeover this week had raised fears that the deal might not take place, but this new offer gives some hope that a transaction might be possible.

Lufthansa has been fighting to contain concessions in its planned purchase of the Austrian carrier ahead of a July 31 deadline to agree a deal as it struggles to limit the costs of the acquisition

Lufthansa had originally agreed to pay up to 377 million euros ($531.3 million) for AUA and has since had to offer the European Union some concessions on lucrative routes. To offset rising costs of the purchase, AUA on Wednesday approved a 150 million euro savings programme.

AUA lost 429 million euros last year and has piled up more than 1 billion euros in debt, or more than five times its equity. It only survived this spring due to a 200 million euro lifeline from the Austrian government, two thirds of which it has used up.
