Arguments for raising the retirement age in the U.S. have been going around for years.

Theyre eager to stay and earn the pay increases and freedoms that come with seniority.

However, there is a limit.

Recently, theres been discussion around raising the maximum age in the U.S. to address a shortage of pilots.

The contributions of more senior pilots may be in training, if not directly in the cockpit.

But those who get hired late say their 40s or 50s will not enjoy either advantage.

So, if youre very senior, its hard to give up the airline career.

After retiring, many pilots pursue second careers as flight trainers or find other jobs in aviation.

Or, if theyre like Manno, they have different plans.

I plan to walk away, to be done flying and call it good, he said.

Manno is a unique case because he hasnt limited his current career to piloting.
