Lufthansa cancels 830 flights with strike to extend to Saturday

German flagship carrier Lufthansa said it was scrapping 830 flights Friday as its pilots went on strike over wages and the union called for the walkout to be extended into Saturday. The strike -- the 14th since April 2014 -- has affected more than 315,000 passengers, with the airline forced to cancel 2,618 flights over three days. The Lufthansa pilots are demanding a pay rise of an average of 3.66 percent per year, retroactive for the past five years.
