oneworld builds on antitrust immunity for British Airways, Iberia and American Airlines

Three members of oneworld - British Airways, American Airlines and Iberia - continued their schedule integration this week by adding an additional 317 routes they will codeshare. Primarily affected by the announcement are the carriers' trans-Atlantic routes, which will now carry the codes of all three partners, making it possible to board, for example, British Airway's Heathrow-San Diego flight with a ticket showing an AA or IB flight number.
