Germany’s flagship carrier Lufthansa has been forced to ground almost 900 flights at airports across the country after pilots began a two-day strike. <br /><br /> The industrial action is part of a long-running pay dispute between the airline and unions. On Tuesday, Lufthansa lost a last ditch attempt to halt the walkout.<br /><br /> Tens of thousands of passengers are expected to be hit by the stoppage. <br /><br /> “Sure, the pilots need to have a certain income, I understand that. But it’s the passengers who suffer,’‘ said one passenger waiting at Frankfurt airport. <br /><br /> “I think there are too many strikes at Lufthansa recently. It’s pretty annoying,” said another.<br /><br /> Unions had initially only called a 24-hour walkout to begin at midnight local time on Wednesday, but at the eleventh-hour said that the strike would continue throughout Thursday, on both long and short-haul flights.<br />
