British Airways (BA, London Heathrow) and Iberia (IB, Madrid Barajas) parent International Airlines Group has officially confirmed that it is reviewing the option of potentially placing a bid for a minority stake in Oneworld partner American Airlines (AA, Dallas/Fort Worth) currently operating under Chapter 11 bankrupty protection. According to United States legislation, the maximum level of foreign airline ownership is however restricted to 25%, so IAG would need additional US partners to be able to place a bid.
