British Airways-owner IAG (ICAG.L) has offered concessions in an attempt to win European Union regulatory approval for its plan to acquire a 25 percent stake in Irish rival Aer Lingus (AERL.I), the European Commission said on Thursday.

The EU competition authority will now decide by July 15 instead of July 1 whether to clear the deal, according to a filing on its site.

Sources told Reuters last week that the Commission was unlikely to approve the stake buy without concessions from IAG to allay competition concerns.
