Last flight of the day

On PHX → PSP, each airline's last flight of the day was cancelled 0.3% of the time, against 1.2% for its earlier flights, so here the last flight is actually the safer one. It arrived 3+ hours late 1.1% of the time (earlier flights: 1.2%). It matters more than the numbers suggest. Miss an earlier flight and there's another one that evening; miss the last one and you're usually waiting until morning.
