Raymond,
Air France: 60, no exceptions that I know of.
KLM: normally 56, maximum 60 if working part time for a certain period before reaching age of 56.
Both these carriers do not employ contract pilots, no difference between FOs and skippers, pilot numbers in the thousands (KLM about 2800, AF far more).
Maximum legal retirement age is 65 for all JAR-states. A heated debate is now erupting since there is mounting pressure from governments and managements to raise retirement age. In Holland there has already been a clash between some pilots wanting to work longer (claiming age discrimination) and the Dutch ALPA defending the retirement age as it is. In France the government recently raised the maximum legal retirement age to 65 from 60, provoking a 4-day strike by AF pilots (retirement age of 60 in AF was not at stake. Yet, that is...)
Good luck,
LH
