A senior management reshuffle will see the bosses of British Airways and Iberia stand down from the board of parent company International Airlines Group.

Keith Williams and Luis Gallego will instead focus on their responsibilities at BA and the Spanish flag carrier respectively from January 1.

At the same time, Antonio Vázquez and Sir Martin Broughton will resign as non-executive chairmen of Iberia and BA, and will continue to focus on their functions as chairman and deputy chairman/senior independent director of IAG.

The role of Iberia chairman and chief executive will be held by Gallego and the role of BA chairman and chief executive will be held by Williams. Both will continue to report into IAG chief executive Willie Walsh.

In addition, Fernando Vives has tendered his resignation as secretary of the IAG board and his current deputy Álvaro López-Jorrín has been appointed to the role. Lucila Rodríguez has been appointed deputy secretary.

The changes mean that the IAG board will be composed of 12 members, of which two will be executive directors – the group chief executive and group chief financial officer.

The changes came as IAG reported October traffic rising 8.9% year on year, with a 4% increase in premium passengers.
