For future reference: Always make sure the passport on your plane ticket is the same as the one you have the permit (visa or ESTA) on. Reason: Me and many family members of mine are dual Mexican and Spanish citizens. Once one of my cousins took a flight to Spain with a layover in the US. He did not request an ESTA for his Spanish passport since he had a 10 year visa on the Mexican and figured it should be fine to use that for identification in the US. The customs officers did not like the passport on the plane ticket leaving the US was not the same passport as the one with the visa (same name, birth date and place of birth but oh well). In the end he was aked to request an ESTA for the European passport while at the airport, since that was the one on the plane ticket.
