Best time of day to fly
On-time rate by scheduled departure hour (local time at PHL). Delays build through the day as late planes knock on, so early flights usually do best.
Last flight of the day

It arrived 3+ hours late 1.9% of the time (earlier flights: 1.8%). It matters more than the numbers suggest.
