Boarding was really disorganized, even though I had requested a wheelchair:( My seat was a bit broken and wouldn t stay up. The food was not as good as it used to be. Except for the crew who were kind and professional , I think Lufthansa needs to make a lot of improvements especially for the tickets prices these days.
