Passengers using the airport in Frankfort,Germany, one of Europe's busiest airports, can expect a second day of flight cancellations because of a ground crew strike.

On Friday, passengers were greeted by long check-in lines and cancellation notifications.

Germany's largest airline, Lufthansa, says it cancelled 300 flights Thursday, stranding thousands of passengers, primarily those on domestic flights.

Authorities anticipate as much as half of the more than 1,000 daily arrivals and departing flights out of Frankfurt Airport could be impacted by Friday's continuation of the strike

The airport operator reportedly has enough help to handle about half of the regular flight schedule on Friday.

The airport strike is part of a larger strike by public service workers across Germany.

The unions and employers remain apart on the percentage of a pay increase.
