Controllers' strike to hit some Air France flights Wednesday

PARIS (Reuters) - Air France will cancel 40 percent of medium-haul flights on Wednesday due to an air traffic controllers' strike, the domestic French network of Air France-KLM said on Tuesday.

The airline also warned of "major traffic disruption" and last-minute cancellations on its short-haul operations at Paris Orly and other French airports.

Two thirds of short-haul Orly flights and 40 percent of flights to and from other French airports operated by its HOP! Air France unit will be cancelled, it said in a statement.

It said almost all long-haul flights would be unaffected.

France's civil aviation authority said controllers had notified it of plans to strike on both Wednesday and Thursday.

The SNCTA controllers' union said in a blog posting that it was protesting about "imprecise" offers from state employers regarding work conditions and retirement plans.
