Air travel disruption after the 2010 Eyjafjallajökull eruption
Almost 640 flights were cancelled in Germany on Jan. 10 as security staff went on strike at three airports, meaning disruption for around 100,000 passengers.
German Company Lufthansa has cancelled 890 flights on Wednesday, including some long - haul flights. As a result, Sofia Airport confirmed that several flights of the company to and from Sofia were also cancelled.
The reason for the strike which started last week is the long - term disagreement between the management and the pilots on the amount of the pilots's remeuneration.
Only two of the ten scheduled flights between Bulgaria's Sofia Airport and Munich and Frankfurt will be conducted on Friday as the pilots of German airline Lufthansa continue their strike.
Short and medium haul flights to Europe, including all flights between Sofia and the two German airports, were cancelled on Wednesday, when the strike began.
