LONDON, July 5 (Reuters) - Lufthansa executives on Friday sought to reassure investors about ITA Airways' financial health after it received EU approval this week to buy 41% stake of the Italian airline.

Chief Executive Carsten Spohr said he expected ITA's business costs to improve further, given Fiumicino airport's efficiency, adding that he was optimistic that a full takeover would be possible after 2027.
