Pilots for Germany's Lufthansa airline have launched a four-day strike over salaries and job security, sending passengers scrambling to find alternate flights.
Pilots walked off the job just after midnight Monday when their union rejected the government's last ditch effort to hold more talks.
Lufthansa has been forced to cancel nearly all its passenger and cargo flights through Thursday. It is apologizing for any inconvenience to travelers.
Lufthansa says the strike could cost it about $34 million per day.
The union is demanding that all Lufthansa pilots, including those who fly for its overseas affiliated airlines, get the same salaries.
The union says this will prevent Lufthansa from moving jobs to other countries where salaries are lower than in Germany.
