Last flight of the day

On MFR → PDX, each airline's last flight of the day was cancelled 0.8% of the time, against 2.3% for its earlier flights, so here the last flight is actually the safer one. It arrived 3+ hours late 0.5% of the time (earlier flights: 0.6%). 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.
