Looks like SSSS still exists, star_world, or would you like to take another crack at explaining that SSSS is a thing of the past when that clearly isn't the case . . .
But i do understand that some airlines no longer print the SSSS on the BP; for whatever reason - I simply do not have the knowledge as to why - a very few airlines no longer print the SSSS. So they can hand write it in (usually what I SSS at SAT), or escort the passenger to the TDC.
