Best time of day to fly
On-time rate by scheduled departure hour (local time at PBI). Delays build through the day as late planes knock on, so early flights usually do best.
Last flight of the day
On PBI → IAH, each airline's last flight of the day was cancelled 0.6% of the time, against 2.2% for its earlier flights, so here the last flight is actually the safer one. It arrived 3+ hours late 2.3% of the time (earlier flights: 0.0%). It matters more than the numbers suggest.
