The Airlines will be fully compliant with GDRP EU regulations. They do not need your consent, only to assure you that all your information is protected under the regulations. (Example, they cannot hold onto your information more than 90 days, etc, unless you agree. Loyalty points systems would require your consent.)One more thing, GDRP does not protect your information from government review and inspection for the purpose of Customs and Immigration review, acceptance or rejection.Have a nice flight!
