Luftansa are apparently on stike and I've noticed a few planes cancelled coming out of Germany. Just a heads up for anyone coming back or maybe going there they may want to check on it before heading the airport. Luckily I'm with airberlin
I phoned up the Lufthansa rep. over in Britain/Manchester, and they said that the Manchester to Hamburg flight should be fine, at least at the moment. Going back I'm a bit more worried about though!
