Finally, my luggage has arrived last night. Unharmed, with all the content.
I have noticed the tag on the suitcase had the correct information:
AF272 flight on the 15th of December, which is the flight I was supposed to take after I missed my connection. So, what happened to my suitcase? I don’t know. I didn’t receive any information.
I now have to find out how to get my money back. I have spent more than 100$ on basic clothes/underwear.
