In response to the pilot’s strike called for tomorrow in Munich, Lufthansa will operate AT LEAST 1 Round Trip between Frankfurt and Munich with a 747-400. It’s too bad that such a rare event has to take place under this kind of circumstance, but if you are in Munich tomorrow between 10:00 and 11:00a, be on the look out for tail #D-ABVY.
There may be another 747 service between FRA and MUC but nothing official has been published by Lufthansa as of yet. This is a saavy way that LH can bypass some of the flights affecting passengers in Munich by rerouting their travel through Frankfurt, thus minimizing inconveniences.
Additionally, it looks like long haul flights are safe for tomorrow since pilots have volunteered to keep the long haul routes going, but there may be some delays to them as far as the afternoon departures are concerned. Lufthansa has also published a list of flights that are cancelled for tomorrow. You can find that info here.
