I think the reason this is becoming a bigger issue now than in the past is that most of the new TSA scanners now scan your ID and not your boarding pass. The new systems match the info on your ID to the airline boarding pass in the system, so a birthday mismatch will flag immediately. In the past, it was only if the agent noticed it when looking at your ID after they scanned the BP - much less likely to flag a concern.

Of course this is part of the boarding pass info. Why do you think you need provide the info every time you buy a ticket? It lets the system perform a check against watchlists, etc. and then TSA matches that you are the same person. I think the system is just now getting tighter with the new ID scanners vs boarding pass scanners.
