You can request a companion pass from some airlines. I know Delta allows it...one of th budget ones do t (Spirit?) Essentially you ask their service desk for a companion pass and tbeu run your ID and print you our a ticket to go through security. I use it because I have family that do not speak English test visits me and I walk them to their gate...but if you just want a hug you can, they don't need a reason to issue one. But I understand what you are saying, and the ability to be at the gate to drop off or meet domestic passengers brought back old memories.
