My British ATPL(H) came to a halt when I was 65. I went to Australia, did the course, passed the exams and obtained an Australian ATPL(H). This I used to fly in Australia, Solomon Islands and China. Then the Chinese CAAC legislated that all pilots flying in China had to have a Chinese licence. Did the medical, passed the exams and got a Chinese licence at 67.
The jobs dried up with the recession but I was fully licenced and had a Class One medical when I finished at 69.
The only time that age came up was when they put a knackered old sod in the LHS. There was something about a total age in the cockpit, (130) but we flew anyway.
