one of the things that make you feel tired after long flights is noise pollution. we don't realize it because it's something we expect during flights but our mind and body is essentially sitting through hours of loud humming that takes a toll on us.

The solution for me is good noise canceling headphones. If you fly often, invest in a good pair and it will do wonders for you. It has for me.

Agreed on noise fatigue. Good -30dB earplugs (worn under headphones if nec), even while sleeping, make me land much better rested (and are ~$0).

Doesn't help with jetlag itself (I.e. the mismatch btw astronomic and biological time), but still a big deal.
