You are guaranteed NOT to get an answer from Lufthansa Airlines for ANY of your problems.
The "contact" address in Liverpool UK for Customer Services does NOT exist !
You will be asked to produce inumerate amounts of paperwork that you dont have, to prove your claim if and when they contact you 5 months later !
After producing the relevant paper work to Lufthansa they will ignore it all and say that they havent received it !!
I hope you are able to get some answers...I certainly havent had any to date !!

An Airline guaranteed to "SORT" you out of your money !!
