 A three-day strike by French air traffic controllers, which began Tuesday, is causing sweeping cancellations and major delays for travelers across Europe, according to press reports. The workers are protesting a proposal by the European Commission to accelerate the integration of air-traffic management systems across Europe. All airlines using French airports have been asked to cancel 50 percent of their services, but flights that cross over French airspace also will be affected, causing further disruption across the continent. The air-traffic controllers are not planning to return to work until Friday morning.
