Lufthansa didn't offer anything to us. I even asked in the lounge for the German Lufthansa number and the lady there said she didn't know and I should just google it. They provided no food or vouchers, no hotel accommodations, no taxi vouchers. It was 8pm at night and we went to the lounge to try and make calls about rebooking and booked our own hotel as most hotels were selling out. We got kicked out of the lounge at 10pm and then tried to get an uber unsuccessfully so we finally took the S bahn around mid night as far as it would go as the entire route wasn't functional so then we walked about 3/4 of a mile in the snow dragging our carry on luggage to get to the hotel. Lufthansa did nothing but say, it's weather related, no assistance at all. We incurred all the expense due to this delay. I submitted a request yesterday for reimbursement of our train tickets, 3 hotel nights, and taxi. If they don't cover all of that then I will go look at my credit card trip interruption insurance to see what they will cover.
