The slots open up next spring.
With a total of 5 Germany flights between LH and NH, I could imagine 2xFRA (midnight and midday), 2xMUC (midday and late evening) and 1xDUS, or something like that, with reduced flights at NRT. Still total overkill.
I *thought* that at one point somebody reported that Haneda-Australia slots were out there and that Virgin Australia was gunning for them. No idea what happened to that entire discussion...
