My flight LH fra to sea due to leave in avout 20 hours was cancelled 2 hours ago! I was not notified by UA or LH even tho this is in the middle of an itin. Ticket was already issued flight still for sale on April 1 the day before the strike! I only found out because I was calling about something else an hour before leaving for my first flight. UA has no explanation how this happened and apparently cannot get any explanation from LH! I have my own suspicions about why they did this, but don't understand how ey can just cancel a ticketed passenger!
