On that particular point, is it a requirement in law for airlines to keep passport data and so on? Is it already in law that airlines must check passports and keep data in that regard? I know that, with certain airlines, people key in their passport number, date of birth, passport expiry date and so on, so the airlines are collecting those data. Are they required in law to do that?
