BRUSSELS, Oct 2 (Reuters) - The European competition watchdog said on Friday it had written to British Airways, American Airlines and Iberia, warning them over their Oneworld transatlantic alliance.
"The European Commission can confirm that in September 2009 it has sent a statement of objections to British Airways, American Airlines and Iberia ... in relation to their proposed cooperation on passenger air transport services on transatlantic routes," it said in a statement.
