Only 10 to 20 percent of flights take place - what does the Lufthansa strike on Wednesday mean for air travelers. If a strike results in cancellations or delays, passengers can make claims.

In general, if flights are canceled or delayed, air travelers are entitled to compensation. However, if the airline can prove that the flight cancellation or delay was due to extraordinary circumstances, the airline is allowed to refuse payment. Using the Flugräger app, claims for delays or cancellations can be made to the airlines.
