I managed to get tickets at 9am but when i tried to register got an error message in german - something about cookies. tried several more times and got tickets again but keep failing to get through the registration. eventually I tried turning some things off on my browser and managed to get one ticket to be told they had just sold out.
I've just looked at flights from birmingham uk to berlin and they cost a fortune so it's just as well I didn't get the tickets as it's too close to christmas to spend so much money to spend on myself. Never mind I can watch on tv.
