This question already has an answer here:
I booked a plane ticket to Argentina with my name as it is on my Tunisian passport. Recently I changed my first name on my french passport so the first name doesn't match the one for the plane ticket/Tunisian passport. So my question is can I travel to Argentina using my Tunisian passport as document of identification and my french passport as a visa/proof of right of entry ? Or the airline may refuse it. Is there any other solution than applying for Argentinian visa with my Tunisian passport ?
