Several different unions representing French Air Traffic Control (ATC) under the French Civil Aviation Authority have called for industrial dispute from June 11 up to June 13, 2013. Controllers are striking over a plan to unify European airspace which will ensure greater efficiency and cope with the projected increase in traffic.
As a consequence, on request of French Civil Aviation, all airlines operating within or to France have to reduce their flight schedules by 50% for this period. This has caused a ripple impact across flights. Greater on medium and short haul flights (domestic France, intra-Europe, North Africa, etc.), and less on long haul flights.
Few operators recommends passengers travelling to or from or within France to contact your airline immediately to determine the level of impact, if any. Many airlines are permitting changes to itineraries without fees.
