There is no maximum age limit for private pilots in the United States, provided they can pass the required FAA medical examinations to prove they are physically and mentally fit to fly. However, for commercial airline pilots (Part 121 operations), there is a mandatory retirement age of 65. This "Age 65 Rule" is a standard safety regulation intended to mitigate risks associated with age-related health declines in high-capacity public transport. Some countries and certain types of charter operations (Part 135) have slightly different rules, and there is ongoing legislative debate about potentially raising the commercial limit further, but as of 2026, the 65-year cap remains the firm standard for major US airlines.
