Ok, I tried going through anonymizer and guess what, it worked. Then I opened up a different browser and tried going straight there and guess what, DID NOT work. This is very interesting and have no idea why I am being denied access.
Then I suggest you contact Lufthansa and ask what’s going on. Go to this page via Anonymizer and send your complaint. Might take a long time before you get a reply, I don’t know, but at least you’ve let them know about it…
