worst experience ever. At the Boarding gate, this one particular African guy racially discriminated me and my sister. we were first in the line to board for Economy glass and he pointed us to come towards him. Demanding us to check in our hand luggage because the flight is full.( their was alot of empty seat on the flight). We informed him that we had already refused the option for checking in hand luggage as i had some important medications and my laptop. He threatened us that we would be missing our flight, and we can wait till everyone is done boarding the flight. When we asked why we are getting held behind when everyone else in the line behind us are getting to board the flight without any issue. He then told us to " stop acting like north Koreans". We told him to look at our passport and that we are not north Korean. He said, " I don't care" His coworkers even came to talk to him to let us go but he said no. I then demanded to speak to supervisor upon which his response was" wait till the end then" The situation was absolutely ridiculous and i had to yell to finally get attention from the Supervisor. The supervisor however was godsent, kind and compassionate lady. She listened to us and apologized on his Behalf. I asked her to get me his name, as i was going to complain about this situation but I was told none to the staff have name badges on them including herself. I emailed Air France (which the complaints department on website was not easy to find), and the response i get back was they are going to work on training their workers on diversity and racial discrimination. Not taking air France again.
