Argentina is said to have detained Air France flight crew who refused to upgrade the daughter of a politician.
Reportedly the daughter of a former Deputy Minister of Justice (and current magistrate) was onboard October 29th Air France flight AF228 from Paris to Buenos Aires. She asked for an upgrade to business class and the crew (correctly) turned her down. She then claimed her seat opponent behaved inappropriately and asked to change seats, which was accommodated (but still not in business class).
