Yeah, first tier on most routes is enough to guarantee overhead space and picking a decent seat. And upgrading a seat for free is worth it as well, but some airlines don't give that to you until the next tier.
I remember years ago I had a flight canceled, and everyone was rushing to be first in line to re-book. I took my time strolling up knowing there wasn't a single person in that line getting a seat before me.
Getting off early, at least on larger flights, is a definite bonus. But I'll usually sit further back to get an aisle or window, and I'll even take the back if I think I can get a seat by myself.
In 2015, I was traveling with 3 colleagues in China for a month. Our host would tell the people at airports (where we were taking domestic flights) that we were "important Americans". We were most certainly not, but he told us this may work to our advantage. Several times it did where we would get escorted onto flights before anyone.
One trip out of Zhengzhou, it went so far as police escorting us through security, to the bar (not kidding) and then onto the plane. At the gate, one cop had a baton that he used to shove people aside while yelling commands at them.
It made me feel guilty at first, but after 4 weeks of traipsing around that country, zero fucks were given when some poor bastard got pushed aside for my sweaty ass to get aboard.
