Maybe the crew has a better grasp on passenger demographics and the JV with IB since they are likely flying it more than you are.


native speakers from their home countries fly AA, but Iberia is Spanish flag carrier...AA flight due to JV is IB flight also. Iberia flights usually are accompanied with the Spanish language. There are also literally tens of millions of Spanish speakers living south of DFW all the way to almost Antarctica. How many Japanese speakers in that geographic range ?
