The airline required checkin at least a 45 minute prior to departure and he didn’t do it. It’s that simple. If the flight wasn’t full he might have been ok.
He didn’t know he needed to be hours early, yet He cleared TSA and got to the gate 30 minutes early. Which is plenty of time, if you’re checked in.
How did he clear TSA without a ticket or being checked in? He should have checked in at the airline counter to get a ticket. How did he clear TSA without it? Significant other (husband?) and a kid. But no bags to check? Probably flying a discount airline.
Trying to blame a crowd of immigrants illegal or otherwise for his self inflicted debacle is disingenuousness at its best. He misses this flight if there is just one person, immigrant or not, on standby.
Sorry, he didn’t fly a discounter. He flew AA. That explains most of it.
