Than you, Mark, for your updates.
I pulled off a last minute scramble to reroute my outbound flight, which was affected by the first (Monday/Tuesday) pilot strike.
For others whose flights may be at risk ...
I booked my itinerary through United, including Lufthansa segments in both directions.
The Lufthansa website said they would notify affected customers on Sunday morning, but I didn't wait for my flight to officially be canceled. I called United on Saturday afternoon and was able to get an earlier flight first thing Sunday morning that avoided Lufthansa.
Fortunately, United already had waivers in place on Saturday afternoon to allow free changes - before Lufthansa notifications were even sent out.
I considered myself lucky that the new itinerary, with 2 connections instead of one, and a night at San Francisco Airport, at least got me in on the same day as originally scheduled.
United refunded my seat upgrade.
It seems I'll need to continue to monitor this closely for my return, which also includes a Lufthansa segment.
