It was very bad, my baggage didn’t arrive resulting in deep loss of money. My next flight to Zurich had to be cancelled, my hotel booking also had to be cancelled. I then had to book flight at Frankfurt airport to get my luggage. I won’t fly this airlines again unless there is no other choice. I highly won’t recommend it also
