I purchased a round trip ticket from Iberia for Los Angeles->Dallas->Madrid. The outbound fights are operated by American Airlines. Return flight is a direct by Iberia. At first, American Airlines confirmation tickets did not show our 2 names. Only one name listed twice. I called twice and waited for a long time to talk to agent. While on the phone with the 2nd agent, our 2 names reappeared suddenly, All appears to be good. So I am not sure this is because the agent fixed it, or their computer just did an update.

The only issue remaining according to the 2nd agent, is that my birthday is listed wrong on the ticket of the first leg Los Angeles->Dallas. He said he can not modify it for me. I will need to go to the counter and show my passport, so they can correct that, before the flight.

Will this be an issue for our flights? Is there any other way to have this corrected before the travel date so I can be cleared of all possible issues?
