I would agree if it were domestic agents, but if airlines will comply if a foreign agent just asks for it, then that is somewhat concerning since its a multinational corporation freely handing over information on private individuals to authorities that don’t have local jurisdiction without so much as a warrant.
Like unless the foreign agents are working in cooperation with the local government, I don’t think for example, an agent of CSIS could walk into an airport in Tokyo and just ask them where Marcus D. Walton flew to or to see their security tapes and expect to get an answer from Japan Airlines without a shit load of red tape.
More likely, that would get them arrested and questioned as to why they’re conducting an illegal investigation of a private individual on foreign soil and probably be seen as an international incident creating a lot of friction between the two nations.
I expect you probably missed that the question denotes foreign agents so no worries.
