American Airlines, British Airways and Iberia are adding more codeshare flights to their trans-Atlantic joint business.
The three airlines teamed up in October to cooperate on trans-Atlantic services without violating U.S. foreign ownership laws. BA combined with Iberia this year to create Europe’s third-largest airline.
Under codeshare agreements, carriers can sell tickets on each other’s flights and frequent flyers can claim points. Airlines say codesharing lets passengers shop around for cheaper fares.
