Sure is, and for good reason! This is a safety sensitive position and the decline with age is real. There are exceptions, sure, but it's not good policy for the industry. Not to mention the fact of changing the rules when it's your turn. Why don't we raise the ATC age to 67 while we're at it! Isn't ATP at 23 also age discrimination? Why can't we have 18 yr old 121 captains?! Or 16?
