Not at all. Some will have less some more at that point in their career.

Say he did fly 750 hours a year That is 15.6 years flying experience. Lets knock off say 1500 hours for time he had before getting hired at Air France that is still 13.6 years line experience at Air France. And that is assuming that he flew an average of 750 hours a year. Which is a bit high given vacation time sick leave training etc.
