Don't want to go against the flow of the subject, but sometimes, LH does something right and it should be mentioned.
On Tuesday, I was flying VIE-FRA-LYS. Arrived in FRA with 15 minutes delay. Only 25 minutes remaining for the connection to FRA-LYS. I made it without problems but luggage did not.
Upon landing in LYS, I received an SMS from LH before reaching the terminal, letting me know that my luggage did not make it and sending me immediately to the lost & found desk.
Luggage was sent on the later flight, arriving at 22:30. Was informed by staff that delivery at hotel will only take place the following day. Then, when staff realized that I was SEN, they informed me that it would be delivered around midnight.
Luggage was in my room by 01:00, not too bad.
