Frankfurt (dpa) - Germany's largest airport is preparing for the planned warning strike of security personnel on Tuesday. A special team is to take care of the passengers who can not get on the plane as planned because of the strike. This includes, for example, the provision of food, blankets and camp beds. The match on Tuesday could largely paralyze the Frankfurt airport. Also at the airports Leipzig / Halle, Dresden and Erfurt Verdi has announced for the Tuesday warning strikes.
