65 is the cutoff. Seriously though, the majors seem to be spreading out the age of new pilots. In the past they hired in waves and hired the same cookie cutter type pilots. Now those pilots are retiring in big waves and causing staffing problems. The majority will probably fall into the usual 30-45 year group, but they seem to be hiring all ages to try to spread out future retirements. Just try to guess what your career path would be at a given airline. If it’s worth it then throw your name in the hat and hope for the best.
