Slightly more than a week ago I had a flight with some co-workers from GRZ via FRA to BER. The flight from GRZ to FRA (with Air Dolomiti/EN) was delayed and we missed the connecting flight from FRA to BER (with Lufthansa/LH). We were rebooked to a flight the next morning.

As I had important things to do in Berlin at the same day, I decided to continue my journey by train rather than plane. And with the service desks at FRA being completely overwhelmed (to the point of people starting to scream at each other) and being somewhat fed-up with the situation myself, I decided to go without my checked-in baggage.

I have since tried to get my baggage back, but have only run into dead ends. What options am I missing?

I have tried the following:

• I have tried to report my missing baggage to Lufthansa on the same day and the next day via their website. The website only said that I should contact "the airline I had my last flight with", i.e. Air Dolomiti

• I sent an e-mail to Air Dolomiti the same day. I got an automated response with a reference number, but not a "file reference number" that would enable me to search on their baggage tracer. I have sent them a pdf form with a detailed description of my baggage several days later, but not received any response. Not even an automated one.

• I filed a missing baggage report with FRA airport. They have sent several automated E-Mails that they have not yet found my baggage.

• I discovered that it is possible to track my baggage via the Lufthansa app, but it was already to late to report it missing. The tracking messages had several "internal errors", but it looked as if my baggage might have been returned to GRZ. (It seems this baggage tracer has in the meantime stopped working at all.)

• I sent a missing baggage form to Lufthansa today

• I have thought about contacting the lost&found department at GRZ airport, but the airport website does not give any contact details for this department.

• I have tried to call the Lufthansa service hotline several times last week, but they either kicked me out of the line or I gave up after waiting up to 45 minutes. Generally my confidence in getting a helpful answer from hotlines is quite low.

Any other ideas? Am I missing something obvious?

Update: I have been able to contact the airport in GRZ, and they said that according to their system, the baggage with my baggage identification tag is already in BER. My next step will then be to try to get the baggage from BER.
