Does Iberia Airlines accept American Airlines tickets?

Iberia and American Airlines both belong to the OneWorld Alliance. Part of this marketing agreement includes each carrier's ability to issue tickets on behalf of the other. Prior to the OneWorld Alliance, AA and IB held a cross-ticketing agreement whereby when there was no local representation for one airline, the other airline could issue tickets on their behalf. This is also supported internationally through their agreements with IATA (The International Air Transport Association).
