Last flight of the day

On KOA → HNL, each airline's last flight of the day was cancelled 1.2% of the time, against 1.6% for its earlier flights, so here the last flight is actually the safer one. It arrived 3+ hours late 0.1% of the time (earlier flights: 0.4%). It matters more than the numbers suggest.
