Pilots Must Retire at 65 Over Cognitive and Physical Decline Risks, So Why Is There No Age Limit for Congress?

The day a commercial airline captain turns 65, their licence to fly a passenger jet expires. It does not matter how sharp they are, how many hours they have logged, or how clean their medical record reads. Federal law grounds them. Yet a member of the United States Congress can keep writing the nation's laws at 80, 85 or 92, with no ceiling on age set anywhere.

That gap drew fresh scrutiny this summer. South Carolina Senator Lindsey Graham died on 11 July 2026, at 71, following a brief illness. No one weighed his replacement against a fitness test. Under state law the governor simply appointed one, Graham's sister Darline, who was sworn in on 14 July, three days later.

At the same time, Kentucky Senator Mitch McConnell, 84, was absent from the chamber after being hospitalised in June following a fall and a bout of pneumonia. He had already frozen mid-sentence in public more than once. No rule can stand him down. He stays until his term ends or the voters decide otherwise.

The pilot number is fixed at 65. The Federal Aviation Administration set the current limit in 2007, after the International Civil Aviation Organization raised the international ceiling to 65 the year before. It covers pilots under Part 121, the category for major passenger and cargo airlines.

Why Pilots Are Grounded at 65

The reasoning is safety. It rests on ageing. Dan Bubb, a former airline pilot and professor at the University of Nevada, Las Vegas, told HuffPost the FAA first fixed an age through medical research. 'In 1959, the Federal Aviation Administration conducted a study,' he said, settling on 60, before later data pushed the figure to 65.

The worry is cognitive as much as physical. Anton Radchenko, an international aviation lawyer and chief executive of AirAdvisor, said the cutoff was built as a precaution against age-related risk. Statistically, he noted, adults over 65 are the group most often and most severely hit by medical emergencies, the kind of event that turns catastrophic at 38,000 feet.

Crucially, the medical system already screens for that. Pilots aged 40 and over must pass a first-class examination every six months, covering vision, hearing, cardiovascular health, and neurological function, with an electrocardiogram each year. A pilot who fails is grounded on the spot. The age-65 line then removes the rest, the ones still passing every test, purely on the birthday. That is the point critics fasten on.

What the Constitution Actually Says

Congress faces no equivalent, neither an age nor an exam. The US Constitution sets only a floor. A candidate for the House of Representatives must be at least 25, a US citizen for seven years, and a resident of their state. Senators must be at least 30 and citizens for nine years. Above that there is no limit, and no medical bar of any kind.

The framers chose that deliberately. They set minimum ages to guarantee some experience, then left the judgment of when a person is too old to voters rather than a statute. A lawmaker stays as long as the electorate keeps returning them. If a seat falls vacant between elections, the fix can be an appointment, as Graham's was, not a fresh test of capacity.

Changing it would be hard. Because the Constitution lists the qualifications for office explicitly, legal scholars broadly agree that a maximum age would need a constitutional amendment. That means two-thirds of both chambers, then ratification by three-quarters of the states, one of the toughest moves in American government.

An Ageing Congress and a Hard Line for Pilots

The contrast is sharp against the makeup of Capitol Hill. The 119th Congress is the third-oldest in US history. The median age in the Senate is 64, a year under the age at which a pilot must hang up their wings. The oldest sitting senator, Iowa Republican Chuck Grassley, is 93, twenty-seven years past a pilot's forced exit.

For that job, members earn a base salary of $174,000 (£130,000), frozen since 2009, and face no term limits, so a career can run for decades. McConnell first took his seat in 1985.

The mismatch has fuelled online frustration. Critics have set the pilot rule against footage of lawmakers freezing or stumbling, McConnell among them. Why, they ask, is a captain answerable for a few hundred passengers retired by law while legislators answerable for millions cannot be? Polling has repeatedly shown strong appetite for age and term limits, even as voters keep the same veterans in place.

So the rules hold where they have for years. A pilot's career ends on a birthday, no matter how well they test. A politician's ends at the ballot box, by resignation, or by death, as Graham's did, with a governor's appointment ready to fill the gap.

No bill to raise the pilot age to 67 has become law, and no amendment to cap congressional age has come close.
