Just a warning, if you are traveling with Lufthansa, they have already canceled 876 flights for Wednesday, due to pilot strikes. While this seems like a large number, it is not the majority of their flights (though a large percentage of them).
The airline said that roughly 100,000 passengers would be affected by the cancellations, which include more than 50 intercontinental flights.
Lufthansa encouraged customers to check the status of their flight online, saying that more than 2,100 flights will operate as usual.
The airline apologized to customers in a statement and said that passengers will not be charged a fee to rebook.
If you think your flight might be affected, it is best to reach out proactively, especially if you are on a codeshare flight (and booked through a different Star Alliance provider).
Either way, good luck if you have an upcoming flight on Lufthansa.
