I've had issues with offshore CSR service before and used this trick, and I wonder if anyone has used it with airlines to get a US based CSR?

When you call for customer service or support you often have the option of selecting Spanish (either form a menu option or via a separate phone number.) When I've done that with tech support and customer service I've usually gotten a person in the US who is either very well versed in English or speaks English natively and Spanish as a secondary language. When you get the CSR you just claims you mysteriously got routed here and they typically help you out in English.

I suspect this works with airlines who off shore, though I primarily fly NW which has most of it's CSRs in the US.
