Spain’s National Securities Market Commission (CNMV) has given the go-ahead for International Airlines Group’s (IAG) revised bid for Spanish carrier Vueling.

The approval clears the way for IAG’s latest €9.25 ($11.90) per share bid, up from an original offer of €7.00 per share which was rejected by Vueling’s management.

Vueling’s shareholders now have until April 19 to consider the offer, which has a minimum acceptance level of 4.16% of the airline’s capital.
