Oneworld says that revenues from the alliance's sales activities rose by a third last year to generate $600 million for its eight member carriers. Almost two-thirds of this was classified as "incremental" revenue – money they would not have earned had it not been for oneworld. Interlining between oneworld carriers generated total revenue of $1.5 billion, up by 30% in 2004 compared to 2003. Oneworld also says it is the first of the alliances to complete the roll-out of interline e-ticketing between all members.
