TR Travel Experience on LH:
We volunteered and got bumped off the flight.
In addition, they rolled out the red carpet surprisingly and really gave us first class service for the rest of the trip. What had happened was the previous flight was cancelled and rather than going with the plan to fly two planes, they needed people to get bumped and go the next day.
They kept our bags overnight and - and allowed us to take one home, which came back heavier

- and when we brought a 6th bag to check in the next day, they said don't worry it's on the house! It would have been $200...
They originally said the comp. was in $ but when the were issuing the voucher I asked them, being that they are a EU airline, don't they need to issue it in euro? They called the supervisor and they looked at past vouchers and said yes, it's euro! That was a difference of 30% so always make sure to ask.
*G (A3) only got us 4 x 50lb. on LH and our carry ons were twice the limit...in DTW *G and Biz class pax. can do curbside check in for free and the agent actually asked to weigh our carry ons....

When he saw the problem, he said no worries - I'll just check one for you (free!)...with the 13 hour layover in FRA planned, that was quite helpful not having to shlep an additional 35lbs...
As I was headed to the airport the next day, I realized that they most likely never reconfirmed SKML and my call to LH confirmed that was the case. They were able to order the FRA-TLV w/o a problem as there was 24 hours left but not on FRA-DTW...as I remembered before, I was able to pick something up.
On the plane, the head steward came out and asked if there was anything he could do and brought out some fruit and nature valley bars.
As far as compensation, they didn't have that much cash at the DTW station so they issued a voucher which can be redeemed for cash at any LH station. When we got to FRA, LH said if you don't want to travel with cash, we can just swipe a CC and issue a credit!
They said it could take a week to post but it only took a couple days. Only catch was that Cap1 systems thought it was a return and subtracted points and I had to call and ask them to credit them back. They did say this happens when a credit is issued even if the original purchase was not made on the Cap1 CC.
In FRA, there are like 6 different lounges you can access, but I just stuck to the Senator lounge (*G). There isn't much kosher food other than fruit. But there was Glenfiddich (14 year, rich oak). As long as there is a shower, wifi and drinks, I'm a happy camper.
An additional plus is that unlike USless Airways, LH lets *G (even in eco) board in the First/Biz lane even if the ticket doesn't say *G which would be the case if you are having the miles post to UA and your *G is w/ A3 or Turkish for example.
(USless Airways refused to allow a second free bag by showing my *G card on a domestic flight and even the supervisor wouldn't budge.
When they lost (delayed to next flight) the bags of many pax. of that flight including 1st pax. with priority bag tags, I asked them to refund the fee and they did.)
All in all, LH went above and beyond and we were quite surprised.
