The prospect of flight cancellations affecting thousands of passengers had already receded on Thursday with the signing of an agreement between Groupe ADP and the company's firefighters.
The firefighters' strike, which began on June 30, resulted last week in the cancellation of hundreds of flights departing from or arriving at Roissy, France's leading airport.
The General Directorate of Civil Aviation (DGAC) had imposed these preventive cancellations in the name of safety: the reduction in the number of available firefighters had made it necessary to close part of the Roissy runways.
