Stuttgart (dpa / lsw) – Stuttgart Airport expects only a minor impact on passengers due to a warning strike announced for Wednesday. The Verdi union has called on Lufthansa ground staff to go on a one-day warning strike over a wage dispute. In Stuttgart, only the Lufthansa connection to Munich is affected, said a spokeswoman for the airport on Monday. Accordingly, four flights from Stuttgart to Munich and back are planned. Passengers of other airlines are not affected by the warning strike.
