Here's one article guys:
I just called Lufthansa to confirm my flight info. They said that if a strike happens starting tomorrow and my flight is affected then Lufthansa will book me on another carrier with no extra charges or fees. This is provided that there are other carriers that are flying from San Diego to Munich, which there are. I checked Travelocity and Expedia, and it looks like there are many other carriers doing that route on 8/30.
So I don't think that we should have too much to worry about.
