Why in the world did the TSA add a checkmark and a trademark symbol to the URL for their TSA Pre✓™ program?
Those characters are even contained in the canonical URL that’s set for the page. If you happen to type in the URL without the two special characters, it 404s instead of helpfully redirecting you to the actual page you were trying to reach. The same thing happens if you type in “/tsa-precheck/” or “/tsa-pre-check/” at the end.
Why? How do they expect anyone to type that? Who thought this was a good idea?
