We strongly doubt this metric has any basis in reality because among numerous other contrary-specific factors, Bloomberg reported that as part of Air France's long-running spat with workers over cost cuts, violence erupted earlier today as protesters stormed a meeting where managers were presenting plans for 2,900 jobs cuts, causing executives to flee with their clothes in tatters.

According to the report, human resources chief Xavier Broseta and Pierre Plissonnier, the head of long-haul flights, scaled an eight-foot high fence to escape, shielded by security guards, with Broseta emerging shirtless and Plissonnier with his suit shredded.

Casting some serious doubt on the service PMI "recovery" is that the attacks happened Monday as Air France told its works council that after the failure of productivity talks with pilots last week some 300 cockpit crew, 900 flight attendants and 1,700 ground staff might have to go.
